Best social networking script?

Looking to integrate social networking to my site, preferably something that integrates with VB - from what I've learned so far phpfox and handshakes are the best out there - but both still have some bugs etc to work out - any feedback on this issue would be appreciated - I know there are a bunch of webmasters out there pondering the same thing -

 

phpfox is good

 

if you want something like digg than use pligg.com

 

I try to use pligg. I think is good.

 

The one I made on my own (http://www.zlitt.com) otherwise I think that pligg is the best one

 

Use Zoints Local. Its perfect for integrating into vB as its a vB social network hack - check vbulletin.org for it
