RocketOn, Inc., a venture-funded startup located in San Francisco, launched a second product called Blerp. With Blerp, users can layer content and comments over whatever site they choose and share their layers with friends. Blerp requires no download and no browser plug-in. Users can go to Blerp.com and see all the discussions that are taking place online. When a user clicks on a discussion, they're taken to the website and can see the blerps (user-generated posts) on the left-hand side of the screen. Each blerp represents either a comment, photo, video, or some other widget that a user has placed on top of the site.
