(two short bonus notes)
1. I live under an internet rock; I had never looked at MetaFilter before today, and was only vaguely aware of its existence at all.
...Wow. Comprehensive! Cool beans. I sense a new timesuck.
2. Carrie! I got your letter; thanks! The red flower on the stamp is lovely. It makes me feel bad for using those tacky, cheap-o Statue of Liberty and American flag stamps all the time. I am going to read it again right now!
