As the NewNet cognoscenti await the outcome of Groupon’s reported board of directors teleconference, I notice there’s a lot of activity surrounding another hyped, fast-growing, and still private social media player. That would be Twitter, that may be adding a money guy to its board and may soon be taking in Kleiner Perkins money. Meanwhile, Twitter integrations go both ways: Google added data from Twitter feeds into its News homepage, while Quora enabled question-following on Twitter’s feed. How will Twitter make its breakthrough? A publisher thinks it’s a publishing problem, that if Twitter can migrate its primary follow mechanism away from people towards “interests,” it will be more valuable to advertisers and users. Perhaps. But Twitter is a two-way communications path, and some people are more interesting than their primary Twitter topics. How would natural language interpretation and pattern-matching handle that?
