So I'd like to hear your experiences with Streetpass, I haven't had much luck myself. Was walking around town on Saturday and although it was crazy busy, my 3DS did not pick up any other 3DS's, but I'll try again next week, maybe go to some game stores :-).

Well, I've only found 1 Mii with Streetpass, and it turned out to be my friend that I ran into on my way to soccer (which he was attending) so I have little experience. I don't know if most people know, but you have to go into the Mii Plaza and turn on Streetpass. Mine didn't come enabled by default.

No way in hell will StreetPass will work in my town.  I guess I could try my Walmart...

I don't walk or take transit, also the town I'm in right now doesn't have people in it who walk or take transit. Even back in my hometown I doubt I'll have any luck. Street pass is quite useless in this country no matter where a person is.

The title of this thread sounds arty somehow. I've had six interactions so far.
 
Your best bet would be to locate a mass/ or fairly sized one's online. There are already Facebook groups and Twitter pages devoted to it. Of course, your own location will play a major role in any opportunities you get, and if you live in an area where your chances are slim, taking it with you to areas which are densily populated with young people, is your best bet. Music festivals would be a prime setting, I can't wait for that in the Summer.  
 
Dedicated sites will pop up eventually.
 
I would give it a while as far natural Street Pass. After spending some time with the trophy thing in SF, something which I mildly mocked beforehand, it's clear things like this will be popular with young gamers. I spent a ton of FP last night on the player slot machine and got myself a Level 7 Juri :P

I take transit on a daily basis, but didn't bring my 3DS with me when I went out today. I'll bring it tomorrow and see if I can catch any fish :)

I take a train & bus to work everyday and sadly I have yet to get any "streetpass notifications", so I assume I haven't encountered anyone with one yet. :( I'm really looking forward to it just so I can see that it's working and because I think it would be an interesting concept to challenge a passer-by to a game I'm playing.
 
I'm kind of surprised I haven't received any yet... I guess it's still too new...

I walked to the bus stop and back and didn't meet anyone. I intended on going into town, but the bus never showed up! 
 
Still, got 9 play coins.

I went to buy some groceries at the local Tesco here in the UK. met 1 person on StreetPass. 
but I think it was because I passed a GAME store on my way there    

I take public transport home from school, and I haven't had anything happen on StreetPass.

I managed to find three people at school, which was three more than I was expecting to find.

I've had my 3ds in sleep mode primarily during my commute into work and back home.  No hits on Monday and even after a lap around my office doesn't seem like anyone here at work has one.  Finally got my first 2 hits yesterday while commuting home. One guy, one girl both of whom had pilotwings listed as their fav title.  Definitely hoping for more hits to continue the Find Mii game.

I'm don't live in the most crowded place, but I have found two Miis. Both of them failed figthing ghosts.

I've met 5 people so far!

i dont really take my 3ds out with me, for fear that i will lose it or drop it, but i definately want to try out streetpass, its a interesting idea, kind of flawed, but interesting to say the least.

"I spent a ton of FP last night on the player slot machine and got myself a Level 7 Juri. "

So, I took my 3DS to my 6th Form/Senior School, thinking that surely that'd be the best place to find people who have 3DSes and wanna StreetPass (in the UK), right? 
 
Wrong, I got zero hits in an entire day. What a disappointment. I even made a visit to Surrey Uni, and nothing.    

No results all day. :( Didn't the 3DS sell like a zillion pre-orders or something? What gives?

Some dude I know that work on a game shop get 15 Miis a day apparently. 

Pick up a random girl called Kelsie in Oxford on my way to the hospital today! No idea who she is, but I found her between bus stops. Mind is blown.

UK Bombers, just go to GAME. they have one set up for StreetPass. I have a feeling it's gonna become a hub for StreetPass.

Got 3 Mii hits and 2 SF4 hits yesterday on the subway ride home.  Seem to be having the most luck on the commute home.  Got my ass kicked in the SF4 figurine battles... probably cuz I didn't know what I was doing and had a team full of level 1 figurines.

I've met 4 people since Sunday.

I've met two so far. One in Target and the other at the mall. Now I think I'll just start following little kids around.

Just had my streetpass cherry popped by a dude who dreams of being a wizard and likes cats, so.... OK, I cheated a little by going to the game store to buy Ghost Recon, really hope the hype is true..

I live in NYC and still have not been able to use street pass

None so far. 
 
I am so going to PAX East next year. Just think of all the Streetpass-ing that will go down once some good games have come out.

Just sit in front of school yard fences, 3DS in pocket and stare. 

I've seen 2-3 kids sitting on the bench outside the local GAME here in portadown, the usually cradle their 3DS in their hands and i'm assuming this is how they intend to fish out other streetpassers.

Going to get my giant SD card, which will hopefully be here on Monday, then I will play around with StreetPass.

The release was a bit unfortunately timed here since all the pre-secondary schools are on sprint break this week. I walk/take the bus to university (near the hub of the city) and carried my 3DS everywhere but no random hits yet. I don’t expect anything until next week and if not then then probably not until ownership has increased more (summer).

So I came across someone today. Got his Mii and did a SSFIV figurine battle with him. That was pretty cool. I won, by the way.

" No results all day. :( Didn't the 3DS sell like a zillion pre-orders or something? What gives? "

I've had my 3DS since Monday and walking around to my classes and errands in Sonoma county (dense for a rural area)  I have so far gotten one mii coming to my plaza. I was quite excited by that single solitary unknown mii.

I don't actually have a 3DS yet, but I'm interested to see how StreetPass will work for me when I do get one.

I live in the city (Melbourne) right near a major train station so I'm hoping students/city workers have street pass on when walking from the station to wherever they're going.

I could just leave streetpass on while it's charging in my room and see how that goes... if it works out I'll totally post here.

this is a pretty cool concept but i dont think it would be effective in places like North America...  well some people that posted up here had a few encounters so i guess its not that bad

More success on the train commute home again. 2 Mii hits (1 repeat) and 2 SF4 hits (1 repeat).  Fared a little better in the SF4 figurine battles this time, won 1 out of 2 (lost to the repeat). 
 
Although its only been a few days, Street Pass for SF4 has been a surprisingly cool feature.  I actually sat there last night re-arranging my team looking at individual figurine stats.  I'm anxious to get get more SF4 hits and see how I do.

Picked up four people just going into town today. Awesome. Only one repeat, too. 
 
So, does anyone know how to beat the ghost with the shield in the little Mii RPG?

Got one streetpass hit the day after I got the system (while riding the train), but havent gotten any since, even though I carry it with me everyday : /  However seeing that green light was pretty awesome :) Wish there was some sorta way to communicate with the people you meet through streetpass.

So far I've gotten four at school and two walking home through one of the more popular hang-out streets and I pretty much can't tell what's going on in SSFIV figurine battles.

I ran into Robeson again today, as well as a girl named "kiwi". The last game she played was Face Raiders.

I turned on the Street Pass for the first time while I was at Wondercon and the first time I checked there were 9 people. As I went through the greeting part I had hit 2 more people. I'm an idiot and I hadn't turned on the SFIV stuff yet so hopefully I'll get some of that action tomorrow. 

No streetpasses for me yet.

Got one hit at the movie theater today. I was shocked, honestly.

I went out to the mall earlier today an had my first four StreetPass encounters.  Of the four, only one or two of them had to have been at the Gamestop.  The others were in completely different parts of the mall.
