For many projects, the single biggest hurdle to success/adoption is good, understandable documentation. Many (perhaps most) open source projects have technical capabilities far in excess of their usable docs.

Look, all you had to do was search for the forums for the the feature that you don't know the name of because it's not properly documented! I don't see the problem here.
Seriously though, documentation is a big deal. Both the "getting started" intro stuff, and the gritty details of more advanced features.
