I have no idea if this will post or not. Even so, I’ll try. It turns out that ScienceBlogs is experiencing technical difficulties and has been since very early this morning. No one can comment (not even me), and some bloggers can’t post (although apparently PZ can).
I have no idea when commenting capability will be restored, which is a shame because today’s post would likely have provoked some interesting comments. On the other hand, it would likely have attracted antivaccinationists as well. Oh, well…
ADDENDUM: The technical glitches seem to have been resolved.
