Smaller Social Networks

How many people do you know with over 300 facebook friends? Most likely, a lot. 

Newer more private social networking sites are being developed to connected with a smaller group of people.  Sites like "Path", users are only allowed about 50 friends or so to only share intimate details with a more controlled group of people.  Additionally more sites are beginning for other uses like moms looking for playdates, RedRover and people wanting to chat in text message groups, Group.me.

After recently being launched in November, "Path" already has hundreds of thousands of users and has accepted about $11.2 million in funding.  The only question now is how long will these sites last? Could they be the next big thing? Or just fads, like MySpace, that people will get bored of and move on to something else?  For now they're all the rage!
