If you're interested in the power of Facebook, but wary of the negative press that it appears to attract, I can recommend NING as an entry-point for 'creating your own social network'. The network can be open and public or private and by invitation only. Initial browsing suggests that a number of US EDUs are using it for Alumni networks.
The free version has Google Ads, but for a monthly fee you can place your own or drop all ads.
Of course, I've been very impressed with the networking aspects of Commun-IT. I'm off to check what's under the hood.
Background info can be found in the cover story of this month's Fast Company magazine...
