Blerp – Say anything anywhere!
Blerp allows you to start discussions right on top of your favorite websites. Unlike typical web comments, you are in full control. You can post on any webpage you choose, regardless of whether they permit user feedback.
In other words, Blerp transforms the entire Web into one giant forum where everyone can participate.
