I've tried to get into Twitter a couple of times now. I go in there, follow a bunch of people that I think would be interesting aaaand then very rarely actually read what they have to say. It just always feel like finding the good stuff on Twitter, even from people I care about, is like finding a needle in a haystack. Most of what gets posted I just don't care about.
I can't remember the last time I bought a CD. In fact, I sold my entire collection on the cheap to some friends and then dumped the rest to an online auction. I just had no use for them anymore and didn't want to lug them around. I moved with them twice and never took them out of the shipping container.
