Here's a serious query:
I've now gotten (in real life) dozens of invitations and requests to join various social networking sites: Facebook, Twitter, LinkedIn, and others with names I cannot remember. The number of such requests has me wondering whether it might not be good to do this kind of thing. Could someone weigh in on this? Are any such sites worth joining? Which ones? Why? What are the benefits? And so on.
I'm inclined to think that all such sites are just time-wasters or instruments of ersatz stalking. Am I wrong? Thanks.
