Ok I fixed up all 4 citations. They have the titles of the articles they link to now and whatnot. It's looking slightly better. Needs more content though. Maybe a history section would help, with dates for when the site launched, when U.S. sales went weekly after NPD flipped out, and when the new Amazon widget was launched. I'd do it but I don't have the dates at hand and I'm about to go to sleep.
