"Thanks for linking to my post on the issues Twitter has in delivering relevant results. It was interesting to go back and read something I'd written so long ago. While my opinions often evolve, this time they haven't. Twitter might get better at being a content discovery service by pushing Tweets that people I follow are Tweeting (aka Summify) but it still doesn't have real search ambitions. It's just ... awful for searching. Breaking news is certainly a strength for Twitter but that only comprises a very small sliver of query intent. It's the crawl at the bottom of CNN, not enough to make Google nervous, particularly since they can easily leverage Google+ and provide a decent 'live' experience. Right now Twitter is evolving and, in my view, will wind up looking a lot more like Tumblr. By making Twitter more visual and locking out third-party copies (watch out Hootsuite) Twitter becomes a destination site which commands attention - the perfect opportunity for advertising." - AJ Kohn
