Usually this is a sign of a project that isn't ready for a lot of attention. It's very brave and a little bit stupid to offer Open Source to the world (especially without a sustainability plan), if you put a lot of effort into 'marketing' at an early stage you've probably just overpromised to people not focused on that domain, won't be able to deliver, and will burn out, and it will become yet another abandoned project.

Perhaps in a few years, as the project picks up uses and contributors, it will get its own website and support network and be easy to understand and use by "anyone."
