Yes, the SurlyRando is now on Facebook! http://www.facebook.com/surlyrando You have to send me a friend request, my Facebook account is all private.
No, this blog will not be shut down. It'll still be used for regular ride reports you've loved. I'm going to use Facebook for real-time ride updates including photos as I'm out on a brevet, permanent, or training ride. I'll continue on with twitter, but it's limited, and I think Facebook updates provides a better reader experience during a ride, with the blog going into greater depth post ride.
