From Scoble post about GReader: >> 3. It makes me feel guilty. I have 1,000 unread items. Twitter doesn’t tell me that.

Actually, I happen to agree with this point. The feed reader tracks what is read and what is unread, and that can develop into a unhealthy habit to check "what is new" and try to "clear the feeds" from unread items several times per day.

Recently, my experience is that GReader (or any feed reader in general) tends to consume quite a lot of time, even too much time. So like Scoble, I am also looking for a better solution, which might include twitter (but twitter lists isn't it for me).
