This is the first of the embedded Waves using the embed api (email@example.com). If you’re in the Wave, you can add comments to this one and see them both here, and on my blog. This really demonstrates a lot of the appeal of Wave for me. Although it’s a bit chicken-and-egg, as it’s still in a relatively closed beta. So if you can’t see anything below, and you don’t have a Wave account. Sorry 🙂
This wave has now been removed, because so has Google Wave. Too bad.
If you want to do the same sort of thing, just add firstname.lastname@example.org to any Wave, and you can get your hands on some embed code, and your Wave ID. Cool, eh?
