"sorry if I am a little pedantic, but Seesmic is not even close to being the first client to support the lists feature. Check out http://talkingpuffin.org/ (support on oct 21st) and dabr (http://thenextweb.com/appetit......), which shows screenshots on Oct 30th.

Oh.. btw, the dabr client which work on both mobile and desktop, is probably the best implementation I've seen as yet, and is super quick" - Shivanand Velmurugan
