A long time ago I discovered this fundamental rule of the net — People come back to places that send them away. Places like Google, Yahoo, Craigslist, Youtube, even Twitter. These are the mainstays. You go there to get somewhere else. Sites that try to suck you in and hold you there, no matter how cleverly, go away. While it may seem like a good approach at first, long-term it’s a losing strategy. ~Dave Winer
