From What Works: The Web Way vs. The Wave Way at blog.enterprise2open.com:
"But then another task needs to be dealt with - protecting users from the complexities of the platform and helping them find ways of use, here usability of apps and sites built upon Wave must be better than what we’ve seen so far … this messy UX above reminds me of some platforms best forgotten."Google Wave complexity does not come so much from a messy UI but rather from lack of etiquette. Once you understand the way it works and you start cleaning up your interactions, you are back to a nice and manageable environment. The stability on the Google Wave sandbox is still an issue, but otherwise using it (as an end user) is easy, and the promise that it will be better than email feels very real.
