This is the official Skribit plugin for WordPress. Skribit is a content suggestion service helping bloggers discover relevant topics to write about from their readers. This plugin makes it easy to add the Skribit sidebar widget and/or Suggestion Tab widget, from which your readers can make or follow suggestions for new posts.
If you want to see an example of what these widgets look like, check out
