It's funny how complicated the barber relationship can get. Thinking of the great Seinfeld episode on that.
Twitter has its place, but so does this place. The volume of posts on Twitter can get overwhelming, and its easy for the quality to get lost in the noise. Plus, as you note, it's hard to compartmentalize topics. So, when I just want to find out what's going on with the weather, I have to wade through a lot of unrelated material. I keep it manageable by only following ~40 people. I don't know how people like you manage following thousands of people.
