Are we sure they haven't done a collective list before? I know 2006 featured separate lists, but the intro to their 2005 recap, for example, ends with "our list." One guy may have written the summaries, but I think that list was a collective one.

I'm starting to get worried.. what if Umbrella actually ends up high in the top 3000? I couldn't look at the list without a disgusted look on my face anymore!
