I was trying to limit myself to 50 subscriptions, but was slipping up toward 60. Is that a lot? Not really?
I just know that I was feeling discouraged when I opened, with some dread, the Reader over the weekend (because I never managed to keep up during the week, which is supposed to be the idea, right?) and was finding upwards of 150 unread posts.
So, to get an idea of reasonable dimensions, I asked a very Internet-oriented friend of mine how many feeds he had: around 30.
Definitely time to sweep up.
