Spent some time today writing up documentation for the skin modifier on the Blender wiki. Most of the tips and tricks for using the modifier should be covered now, and each section has a (hopefully useful) example image.
This page will be moved to the release notes once the skin modifier is in trunk, so it could definitely use some nice user examples. If you create something with the skin modifier you think would look nice on this page, send a link. (It doesn’t need to be just the skin modifier; some sculpted examples would be nice too, especially if you can show the original skinned output too.)
In addition to documentation work, I’ve pushed some improvements to the topology generation. It is a lot more stable now around branch nodes. Although folding still occurs, it’s getting reasonably hard to generate a non-manifold mesh.
I’m also starting to enjoy playing with the skin modifier; it’s just fun to doodle with :) I don’t really use Blender as an art tool, but occasionally it’s nice to just play with all the cool tools.
