AIR: A runtime for Twitter clients?
The most interesting product of Twitter’s popularity, to me, has been the explosion of Twitter API client software. There are a slew of cross-platform Adobe Air-based clients, including Twhirl and TweetDeck. TweetDeck in particular appears to be the most popular interface for Twitter other than the Twitter.com web site. (One could be forgiven for assuming the entire point of Air is to serve as a runtime for cross-platform Twitter clients.)
