Advertisers and marketers -
Have you found a way to integrate your product or service as an application/feature in Facebook?
You are fools if you haven't.
As mentioned at Outfront, this type of marketing pattern flows seamlessly with the audience using Facebook. If your Facebook gadget serves a Facebook profile need or want, your name will gladly be plastered on a user's profile in conjunction with said feature.
Look at Washingtonpost.com's Political Compass. Since release, the application is now tacked 137,309 profiles. OK - it's not a gigantic amount relative to Facebook's total population, but for free advertising it's impressive.
UPDATE: In the nearly 10 minutes since I wrote the above paragraph, the compass usage statistic has jumped to 137,687 total users.
