I follow people I know personally, services and businesses I use regularly, and people I’ve met and have some sort of ongoing connection to (but aren’t “friends” or acquaintances). Everything else gets added to a list, and especially noisy twitterers (not a fixed rule, but if you update > dozen times an hour) get added to a list and unfollowed. I find accounts by very occasionally strolling through my followers and the followers/followees of people I follow, or through blogs/articles I like, or people who interact with me who are not bots. I've set a soft limit of 200 for myself for accounts to follow, it once was over 1000 but I just found that useless in all twitter clients. I unfollowed almost all celebrities, almost all bloggers I regularly read anyway, and really tried hard to cut it down to people or services I had some sort of connection to. Though I understand the reasoning, the inability to match email accounts to twitter ids is annoying as I frequently discover that someone I know is on twitter entirely by accident.
