Minor issue- The signaling of using a ".com" rather than a ".org" address makes the website appear to be slightly cranky. It is a tiny signal but it is one of the first things people will notice. I don't quite understand what Bostrom was thinking.
.com seems to have established itself as the generic domain that's used for everything. I doubt most people even notice (I didn't), even though .org would probably be slightly better.
