Hey! I'll have you know I loved Google Wave. :)

Kidding aside, Google Wave is an interesting case because it's a product that actually was very popular, just in a use case that was completely different than what it was intended for, and in a way that didn't serve Google. Many startups/companies were using Google Wave as a simple project collaboration tool, and honestly, I still think it was one of the better tools out there for that, and I haven't found a decent replacement.
