I love my blog, and it keeps me quite organized. It's like a web-accessible look at major things I've done.
One of the neatest tips is to google a search term at "site:penn.typepad.com" (or whatever site you want). Example: Google "SCA site:penn.typepad.com" and you'll see every time I mentioned the SCA.
My latest reason for loving my blog is having the date of my general GRE. The score report just gives the month and the year, and Yale wants the day. I was fairly sure when I took it, but I couldn't remember perfectly. So, I went to my archives for Aug 2004 and found this post.
Huzzah for the blog!
