Even indie devs should not be alone throughout development. The outside world is a helpful tool for development. I'm still waiting for the day where I can go to Game Developers Conference and meet countless other developers in person to just talk about game development. I'm even trying to find other indie devs at my school just to connect with someone doing the same stuff I'm doing now. Until then, websites like Gamasutra can fill in my need for a sense of community.
