What “beta” means in a web site name:

Sorry, we’re not telling you the truth about our service and the benefits, and that’s why we’re calling the service beta; once we’ve found out how to do it right and still earn some money with it, we’ll remove the beta sign.

Especially liked the MySpace example.  I was especially surprised to find that Ted Haggard was “in my network” (when he had a MySpace page.)
