One of the greatest things about the Twitter native apps were that the guy who originally wrote them (Loren Brichter, who Twitter acqui-hired) literally invented the Pull-to-refresh gesture that is used everywhere nowadays. Before Twitter killed native clients by restricting their acccess tokens, they were an amazing place for people to try out new UI ideas - a really simple concept (one text area and a scrolling list) but a huge explosion of ways of presenting and interacting with it. Then twitter bought Tweetie and Twetdeck and restricted what the 3rd party clients could do and it all just died.
