These are all about Thanks. There are two interesting links here. One is the link to a Thank-you from Phil Plait on his Bad Astronomy Blog. Then he, in turn, links to this really cool video thank you by Ze Frank on his blog.
Okay, Ze Frank's video blog is funny. I just watched the 27 November entry about Scrabble. Hah!
(But caution, there is some PG-17 language and maybe more).
