I forgot to mention it here earlier, but my Warcraft Year in Review Meme, in addition to spreading organically through peeps tagging each other with it, was the holiday time shared topic over on Blog Azeroth. Lots of great year end wrap-up posts both in my post's comments and on the BA site.
If you're not familiar with Blog Azeroth already, and you're blogging about Warcraft, I encourage you to head over there and check it out. Lots of good resources for many of the popular blogging platforms, plus lots of ideas for getting post ideas flowing, including the weekly/biweekly shared topics. They also maintain a twitter warcraft blogger list.
