Gartner Group released their Magic Quadrant for Social Software towards the end of last year and I came across it today while doing some research.  It was great to see cool company Socialtext featured in the analysis although that is a bit hard to determine when you look at the quadrant itself.  Guess it's fair to say there are no true leaders in this market yet but definitely plenty of players.  Think they could have crammed any more companies in the bottom left?
