How many log-ins do we need?

Maybe it's my OCD talking but lately I feel like I have way to many accounts scattered around the internet. The recent PSN outage (yeah I know you don't want to hear anything more about it) had me scouring the internetz changing passwords at around 40 different websites. As I was doing this I just couldn't help but think that a lot of these accounts are worthless. I don't use them for anything, I just made them and forgot about them. I was looking through my archived mail and saw account confirmations from websites I don't remember visiting. I mean, why the hell do I need a animefreak account. I don't chat or comment on the website. You can watch the videos without an account so whats the point. I know i'm going on and on but for some reason it bothers me to have my info on so many websites when its unnecessary. Thats why today I'm going to go around and delete quite a few accounts that I don't use for anything. Am I the only one?
