This is probably old news to most of you, but I finally realized: my email inbox is fast becoming only useful for official communication, companies (and some clients) talking to me. It’s not where I talk with my friends, mostly. Then again, I’m no twitter/facebook fanboy either, as many people seem to be these days, so I’m not sure what may happen next. But definitely: there’s an opportunity there, I’m thinking mostly about small group conversations. A few startups are gunning for it, but I haven’t seen anything I like yet.
