Care to elaborate? OR you (think) don't have to do that either? :)
I don't recommend people because I hope they'll recommend me back or because I'm thinking about building a social structure; I do it if and when it'd help the person I'm recommending them to if and when it'd be natural to do so.
Watching you guys talk about building the social structure and networking reminds me of watching a psychopath try to fit in with normal people and learn when it's appropriate to smile or fake emotion. You're talking about actively learning to manipulate people to your advantage, I just don't find that cool, even if it is to everyone's advantage.
