Note from JWR:

Please refrain from trying to have me join you Twitter, Facebook, or any of the other social networks. Getting more than 150 e-mails per day is overwhelming, but an extra 20 to 30 e-mails proclaiming that “John Smith is following you on Twitter” is distracting to to point of annoyance. I don’t respond to any of these requests. I simply don’t have twime to tweet. Thwanks!
