Why Wave Failed
Florian Wardell submitted a little discussion piece about Why Wave Failed. He blames marketing and the staged rollout. Personally I think that what killed it was that I should have transparently been able to see my gmail inside wave. Requiring a separate window guarantees that I wouldn't use it regularly. Had I been able to read my regular mail in the same UI, I might have been tempted to use it more.
Troll harder!
Oh, wait...
Troll... a drink with jam and bread?
