Another site update. There are several minor changes, and one big one: comment posting. It's pretty basic for now; as the site evolves new capabilities will be added.

It's been a little while since the site launch, but I've been busy with some updates. Most of them aren't user-visible just yet, but are necessary for the upcoming registration and comment system.

The one notable exception is the new tag cloud, which will be the subject of an upcoming article.
