...if not downright narcoleptic.
A couple of you have mailed me privately and said that Haloscan is rejecting attempts to comment here (enrevanche, which predates decent commenting functionality in Blogger, uses Haloscan to provide comments and trackback functionality.)
If I can figure out how to submit a trouble ticket with Haloscan, I will. Gah. For now, hang in there and hope that this is just transient weirdness - also, try clearing any Haloscan-labelled cookies on your browser, if you're technically inclined.
