i'm looking to launch a social networking website on a particular topic...been looking at the various solutions out there. if anyone has any firsthand knowledge/recommendations i'd appreciate it.
the site will be a niche site where I know a lot of people in that niche. hopefully they will be happy to join a social network that caters to that area...the site itself is only part of the website which will be a portal-destination.
and thanks to all the advise so far....some of those sites I had not heard of before.
