These things went from the hottest online commodity (selling on eBay, etc) to something that can't be given away. I think there's a conundrum — nobody is using Google Wave because there weren't enough people on it to begin with, but now people aren't interested in the invites because they hear nobody is finding a use for it. This wasn't an issue with Gmail because it worked with all other email systems, whereas Wave is having to build its user base from the ground up. I'm sure it's been discussed in numerous other threads, but is anyone genuinely using Wave for anything productive?
