It was brought to my attention that there were Javascript errors on the page, and that may have caused a few issues.
The issue at hand seems to be that the blog ring thing, which is based on an external Javascript file, for some odd reason is down and that code referencing it failed.
This may have led to other undesirable effects, like being unable to post comments. Sorry about that!
The blog ring code has been disabled until this is sorted out, but apart from that things should work as usual.
