Why most online communities are failures

As anyone who has started their own blog certainly knows, it takes all of an hour (if that) to create your very own space to share your most brilliant ponderings for the entire world to see. But when it comes to building a space online that people want to visit regularly and contribute to, well, most of us never get there, and for good reason. It's really hard. Plenty of smart companies and organizations have put together their own online communities. Some are pulling this off brilliantly; others, not so much.

Why should companies care about these online communities? For one, they can increase the value derived from, and the lifespan of, a company's customer relationships. But more broadly, online communities can become valuable tools to understand how customers use a company's products or services and what kinds of improvements or changes might make sense. Companies pay a lot for focus groups and yet virtual communities represent a kind of 24-7 focus group.
