I got on Twitter when +Robert Scoble
was cheerleading it, around 2004 I think it was, maybe earlier. For a few years, it was valuable, good conversations in 140 characters. The past few years, I post tweets sporadically, and find it has too much noise and the short message length makes real conversations very difficult.
Plus, they changed the user interface and messed it up. The original Twitter was sleek and easy to use. The New Twitter is a design disaster, with, for example, DMs and @ replies in different tabs, which makes no sense at all.
