It's certainly a tumultuous time if you've based your business on a "feature" of Twitter that it could feasibly replicate itself. http://tweetup.com http://tweetup.com launched just yesterday proclaiming their advertising value-add to the Twitter ecosystem. The atmosphere there must be pretty tense today... As for Promoted Tweets, I wonder how this affects the ToS for people who are already using one of those tweet-brokering services. Are those services now dead in the water? What about if you take direct payments for a sponsored tweet and thus circumvent Twitter's ad platform - will this be against the new ToS?
