Speaks the truth.

One of the biggest hurdles to building community is registration. Many people will consider participation in your community, and are turned off by any registration process. Most blogs dodge this hurdle by not requiring membership to post a comment. This may bring the threshold low enough to get comments but does so at the expense of a continuity in user identity. Those who post have made very little commitment to the community and have no strings connecting their comment back to them, their larger online community or even to their other posts on the same blog.

Platforms like FacebookConnect and Disqus attempt to solve this problem. While these services may lower the barrier to participation while maintaining a consistent user identity, you still must acquire participants in your community one person at a time. And you will only do this by offering them something of value.
