I'm not quite sure how the Featured Blog thingy works, but I created a blog this morning about Universal's movie download service and noticed that PHP/vBulletin/something munged the apostrophes in the title when the blog suddenly appeared in the Featured Blog section. I went back to correct it (and add a note to say I had to change the title due to the problematic parsing of the title) and then found the blog had dropped entirely out of Featured Blogs..
Does that mean I've been naughty? :)
