Is there an escape the social networking invitiation merry-go-round? There must be a way to easily configure your Internet service and/or computer to block anyone trying to send you a LinkedIn and Plaxo invitation. I find them annoying, intrusive and impersonal. Sorry for the foot-stomping rant but Alec Saunders sent me an invitation to join his Doostang (a very silly name, by the way!) network. I quickly spiked it - Alec, you're already on my "unofficial"social networking list - since I regard these invitation as a form of spam. If you want to establish a  link, call or e-mail me. Now, if anyone can let me know about an anti-Plaxo or anti-LinkedIn service, that would be useful.
