>"There is no "patent" on... creating a more durable (and by that I mean self sustainable) service which has the same capability." I'd love to hear why you believe going from a decentralized open shared system like RSS to a centralized proprietary system controlled by one corporation (Google+) is even conceivably more "durable." I'd bet $100 that Google+ sharing will be dead and buried long before RSS goes anywhere.
I wouldn't bet against a lot of money (google) shutting down something they have seemed to bet a lot on. I believe Google shutting down Google Reader already means that 'RSS has gone somewhere' or will on July 1.. [edit] I also think Google backing off the shutdown would show a lot of users that it does listen and is willing to continue running a sub-par unit instead of shutting it down.
You mean like google wave?
Or checkout?
Or google buzz?
Or any one of a large number of other products / projects that are no longer.
