For the 1 million users who are still using Google Wave more than a year since it was created, Google is making it easier for users to grab content from the Web into a wave. Users previously had to cut and paste Web info into a wave. WaveThis is a button, bookmarklet and Chrome extension that lets users launch a discussion in a wave directly from the site users want to share. WaveThis works like the retweet button on Twitter, or the new reshare button on Google Buzz .
