Apparently, Left2Right had a problem with someone hacking the comments. David Velleman wrote:
This afternoon Left2Right was vandalized by an attacker whom we have previously tried but failed to ban from the site. Since I will not be available to scrub the grafitti off the walls, I have eliminated comments, at least for the rest of the summer.Bummer!
However, I will make a comment thread available for every Left2Right post this summer, except for one week when I'm on vacation. I don't know if anyone will find the comment threads since there's no trackback available at Left2Right either, but I'll give it a shot anyway.
I'll create comment threads for the last few posts at Left2Right tomorrow.
