s/Wave/Paper in this Wave obituary from 2010:
> Wave brought together elements of instant messaging, e-mail, microblogging, and collaborative editing in a single service that strongly emphasized concurrency and rich media. ... Despite its prodigious sophistication under the hood, the service never resonated with its target audience. Regular end users saw it as a mismatched amalgamation of disparate messaging paradigms blended together in a cumbersome Web-based interface.
