I tried to use Wave to collaborate on a blog post with friends, rather than emailing each other critiques.
They thought it seemed to complicated and stuck with email.
I’m haphazarding a guess that maybe Google didn’t stick with it because, if I recall, most if not all of their services were free and this one probably cost a lot to run without a clear monetization strategy. If it didn’t increase the size of a captive audience, and they weren’t willing to show ads in the product itself, and they weren’t going to get better data from users to inform their ad services elsewhere…why run it?
Of course that’s all speculation.
I thought it was used as a vehicle to have users agree to a much more “we can do whatever we want with your data” tos. From that standpoint i guess it was successful, everyone signed up.
