Grrr
The thing I dislike the most about Gnome is how little information for developers there seems to be. Trying to find something about how the thumbnailer is supposed to be incorporated into a project, I just find patches and blog entries, not actual documentation. Given that many other projects have no such problem, and Gnome apparently has no problem writing all manner of other stuff. This is not the first time either. This really delays adoption of the good stuff that there truly is in Gnome.
