Internet TV site Current TV and microblogging platform Twitter are teaming up for interactive coverage of the Oct 7 presidential debate.

The project overlays real-time Twitter posts over a live broadcast of the debate.

Here’s how it works:

• Tune in on October 7th at 9pm EST/ 6pm PST for the Live Presidential Debate. Find Current TV on your local cable/satellite provider or watch it at the Current site.
• Make sure you’ve registered with Twitter to participate.
• During the debates, chime in by including “#current” in your tweet. Example:
  “This discussion about universal healthcare makes me want to pop some pills! #current”
• Current plans to display as many “tweets” as it can. You can see all of the #current tweets by searching #current on Twitter search.
• Questions? tweet @current.
