I agree and disagree. The fact that a giant company tried it and failed, and the fact that Apache Wave just sits there unused both suggest that there likely isn't a business there, but there have been many occasions where a company markets more or less exactly what has been tried unsuccessfully before a tad differently and it suddenly takes off like wildfire.

I would not at all be surprised if something Wave-ish became a huge deal someday, not would I be surprised if a dozen companies tried it and failed before someone makes it work.
