I really like Damus, but I notice that when I refer new users to it they find it confusing and quit in the face of the unclear UI. I think if you aren’t previously exposed to Tweetdeck that it is a confusing experience. I loved Tweetdeck but it wasn’t a wildly successful product. Old Tweetdeck was the best Twitter client, but I had tons of complicated search columns. Normal users don’t need these features.
