Are you kidding, Fred? It's more like these plazas you see around
Manhattan which have a little plate set in the concrete saying that
"Easement is revocable at will" or some such -- specifically denying
that any "right" was created just because they put up a fountain and
trees and a few benches.
Jimbo doesn't have to keep this site going. And WikiMedia CAN suddenly
shut it down or go commercial or (shudder) pro-Marxist at any time...
There's no contract. No rights. You and me and mav and thousands of
others have only 1 right: the right to fork. But we are all LITERALLY
"allowed" to post at Jimbo's whim.
Gradually the committees are putting Jimbo out of the "whim business" so
there's a bit of transition going on. But I can shut down the whole
thing anytime with 2 mouse-clicks, and I wouldn't be violating your
rights in any way.
Firmly (but fondly),
Uncle Ed
