Twubs a' Twitter & Ning a ling & what?

Well, from that ominous sounding title you'd think I was going to either be laying down some crazy rap or maybe some ee cummings lines (dr seuss, perhaps) but no, just an embedded twub. Who are all these people Twittering hopefully and brightly in the cold cyber atmosphere? But not alone they are: you are here with them, hoping, waiting, wondering. Social network.
