But email was already interoperable. GMail offered a nice interface, lots of storage, and a good spam filter, but otherwise it was just email. You didn't need to have friends with it to benefit from it.

Having used Wave, it was very taxing on low-end computers, so I never ended up using the fancier features - we used it for a group live-watch of LOST every week with several other friends.
