Why Twitter’s users are in open revolt

Twitter is planning to debut a Facebook-style, algorithmically curated newsfeed -- provoking a backlash among Twitter users. In addition, the image-sharing site Twitpic announced that it was shutting down amid legal pressure from Twitter over Twitpic's trademark application. According to Twitpic, Twitter threatened to revoke Twitpic's access to Twitter's systems if it moved forward with its trademark application. That news is inspiring even more criticism of Twitter as the service seeks a foothold among non-power-users and tries to expand its appeal.
