Linked-In is getting quite egotistical and annoying. When I try to invited folks, I get a message indicating I'm not allowed to invite anyone - but I have only 926 connections - far fewer than the 2-3K allowed (is it 2k now?).
I think they'd make far more money selling commercial ads on the site and letting it wide-open for all users to interconnect than charging the user or restricting free/paid members.
Anyone can invite me to join their linked-in connections via my profile:
