Restoring Chizumatic‘s sidebar to its rightful place was a task worth pursuing, but since the Minx templates generate tag soup, standard validation tools produced too many errors to help much (W3C’s produced ~700 errors, compared to this page’s 16, 14 of which are parser errors in Amazon search URLs).

So I tried a different approach:

#!/usr/bin/perl
while (<STDIN>) {
    chomp;
    next unless /<\/?div/i;
    if (@x = /<div/gi) {
        print "[$l] $. ",@x+0," $_\n";
        $l += @x;
    }
    if (@x = /<\/div/gi) {
        print "[$l] $. ",@x+0," $_\n";
        $l -= @x;
    }
}
print "[$l]\n";

Skimming through the output, I saw that the inline comments started at level 6, until I reached comment 8 in the “Shingu 20” entry, which started at level 7. Sure enough, what should have been a (pardon my french) <tt></div></p></div></tt> in the previous comment was just a <tt></p></div></tt>.

[Update: fixing one bad Amazon URL removed 14 of the 16 validation errors on this page, and correcting a Movable Type auto-formatting error got rid of the other two. See, validation is easy! :-)]
