For the uninitiated, Wonder Trade is a new online feature that lets you select a pokemon to trade, and then randomly hooks you up with someone else and has you trade with them. It's an interesting way of getting rid of pokemon without just releasing/deleting them.
Internet opinion on Wonder Trade seems really mixed, so I thought I'd try to get some numbers. Personally, my very first trade got me a Kadabra (which instantly became an Allakazam) so my introduction to the feature was pretty excellent. I also got a Croagunk, a pokemon I'm very fond of but never found in the wild, and a french Haunter, who became a french Gengar.
Of course, intermixed in all that were tons of caterpies and bidoofs.
I recently threw a bunch of level 1 squirtles and tyranitaurs into Wonder Trade, and it's a good feeling. It's like being some kind of weird secret Santa to random strangers, especially when they message back a thanks.
