And does anyone actually use quora to find answers to questions, rather than to promote themselves as answerers of questions?
And does anyone actually use linkedin to find jobs or contacts, rather than as a personal advertisement / to demonstrate your linked-in-ness? Are those things one and the same?
These are supposed to be such Big Things that demonstrate the importance of social networking (twitter especially) but I don't really see them being used except for the sake of using them... (unlike facebook, blogs, etc.)
Am I misguided in thinking the userbase is the correct measure of importance? Maybe it's the ubiquity of those little sidebar boxes with tweets pertaining to the subject of the page / tv newscast / etc.? (Am I in the minority in finding those not much less irritating than youtube comments?) Or the availability of answers in google, or the availability of contact information for industry professionals?
