Uh-oh. Are there any other companies than Whisper System that had an actual end-user product that Twitter has acquired -- and then not killed off? I don't recognize that many from: https://en.wikipedia.org/wiki/List_of_mergers_and_acquisitio... Except for Dabble DB (Smallthought Systems) and Posterous: http://blog.dabbledb.com/2010/06/140character-dabbling.html http://www.theverge.com/2013/4/30/4281780/posterous-is-s…
I'm sure there are others, but these are the ones I know off the top of my head: * Summize -> search.twitter.com * Tweetie -> Twitter for iPhone * TweetDeck * Vine * Crashlytics * MoPub * Gnip
Thanks, I suppose I should have been a little more specific -- I'm not surprised Summize, Tweetie, Gnip and TweetDeck lives on. That said, Crashlytics, MoPub and Vine does seem to indicate that not every Twitter acquisition of an "independent" product leads to product death.
