On a personal note, today happens to be my and Hannah's half-birthday. I didn't know we had the same birthday until today.
I also want to add, on the heels of my last post, that I don't think the people making these women in science blogging link fests are doing anything bad. Traffic-sharing is good. I just think people need to realize that this isn't really solving any problems.
