How to launch an open source project…help…

We all can cite many open source and even some “closed” source projects that we use and interact with daily.  How did they start?  Most of them started out of the passions of a single individual, but how did that spread?  How did people find out about the projects, how did others start building on these projects?

I ask, because I’ve just put out my CMS for Google App Engine (it’s pre-alpha) and looking for people who are interested in playing with it, giving me feedback, helping it improve.    The challenge is out side of nagging on my friends — amost feels like nagging on them to change jobs — I’m uncertain where to start.

I’m going to continue plugging away, but if anybody know how to evangelise or create community that would help.

For those interested (please) the project is here:
