It's preposterous for him to prescribe how others should use twitter. Besides, I don't read each and every email I get either.

The thing is I do not trust an algorithm (or popularity) to accurately tag what an "important" tweet is to me. So I tend to follow single-purpose accounts with high signal to noise ratio - if I follow you for your insights in algorithms; serial-tweeting your cat pics will get lead me to unfollow you. I know I miss out on a lot of C.Sci wisdom from people who tweet prodigiously, which is a shame

I wish twitter had user-defined 'channels' like @user/cuda and @user/cats so I can selectively follow a specific channel that interests me...
