Please. Somehow I doubt that Jason Fried, of all people, is losing sleep because of a vaporware product in a completely different space.

Or do you think that somehow Diaspora will be a product management solution? Will it also do my taxes? Perhaps it will print bingo cards, organize my book collection, and bake the world's tastiest pies?

This is exactly what Fried is talking about: When you launch a pure-vapor product you encourage people to project fantasies onto it. That sends you lots and lots of false signals and sets the public up to be disappointed.
