Rounding up the post mortems on Twitter’s announcements. Colleen Taylor says Twitter’s photo sharing service will bring new life to Photobucket, the company that’s powering it. The product demo shows some nice search and hashtag integration for discovery, but no evidence of advertising opportunities for Twitter. And it’s aimed less at collections and more at real-time photos – there were 2 million photo links in tweets on May 30 – and thus, at Twitpic and Yfrog, rather than Facebook or Instagram. Matthew Ingram thinks Twitter’s search improvements still have a ways to go. You still can’t search an archive older than a week, and it’s not very clear how Twitter’s personalization and relevancy ranking works. Meanwhile Darrell Etherington scoffs at some who think Apple would build a Twitter competitor. I don’t see how Apple would monetize such a thing any better than Twitter does, and if it wanted to increase habitual usage of its hardware, it should just integrate Twitter more deeply into the iPhone. Which it may be doing.
