It seems that the old fogey's at ScienceBlogs have discovered facebook and started to add their profiles ;)
You should head over there and join some of the related groups that have popped up (and make friends with some of the old folk!) - starting with me and the ScienceBlogs fan club. If that's not enough there's the Order of the Science Scouts of Exemplary Repute and Above Average Physique.
