What is the most impostant for you in social networking sites?

That it's liberal, not politically but in terms of rules and restrictions. Some such sites attract the kind who derives a sense of power out of their enforcement. At typical such site an "administrator" frequently interrupts a posting to announce a violation of some arbitrary rule. One such site threatened to suspend the participant if he spelled some words differently than expected

Incidentally a2k is the most liberal I've yet encountered, lets you get away with practically anything

Thanks for your reply!
I agree with you, that's good that it is liberal,
