A few weeks ago, I noticed a new feature{.vt-p} of Google Wave that allowed a user to easily send websites and content to a new wave to easily share with others. The feature (called “Wave This”) was not officially announced at the time, and I was asked politely not to say anything more at the time until the team could officially announce it.

In addition to this, the Wave This{.vt-p} function has an official Chrome Extension{.vt-p}. Install the extension, and you can send any page to Wave with a click!

Finally, you can also use an undocumented Wave This feature to add a Wave contact button to your sites. At the top of my page I’ve added a “Wave @ me!” button that starts a new wave with me as a participant so you can easily contact me in Google Wave. To add the button to your own site it’s as easy as filling your details in the code below:

<a href="https://wave.google.com/wave/wavethis?t=Contact+via+[Your-Site-Name]&r=[fill-in-your-@-wave-address-here]" title="Contact me in Google Wave" class="vt-p">

The &r parameter for adding a recipient isn’t listed on the API page and support might be pulled or altered so use at your own risk. Additionally, be aware that the Wave This function currently defaults to the Google Wave Preview account only, so if you use a different client (a Google Wave for Domain Apps account for instance, or Novell Pulse) you’re out of luck for now.

So there you have it! A new API, an awesome function, and my modest widget. Have at it! Make some buttons Start spreading Wave!
