We have created
pullrequest.org (s french developer oriented blog) a week ago, and have chosen to use
node-yabe which is small yet smart and actively developed. It is heavily inspired by Wheat and he extracted some code coming from it, and the genral strcute too. The author of node-yabe, Mickael Daniel, currently uses a modified version of Wheat for his own blog (
http://blog.mklog.fr, I guess he plans to move to yabe next)
Our first guess was to use Wheat, but we weren't comfortable with haml and prefered jqtpl notably, and we wanted to make some back-office in order to help using the git repository (pulling, etc.) and writing articles. Wheat is fine but not everything was clear for us while reading the sources, which is more the case ion yabe.
Node-yabe just runs on the filesystem without relying on git, but we are working on a node-gitteh integration (if possible more like a plugin, so we plan to implement a plugin system) and mickael is working on a back office using Ace to write articles ( Michael is in our city, and we just met him some weeks ago, and shared our point of view)
By the way, Wheat is a pretty good blog and we were really happy to find it at first :)
