Last night Facebook added a new wiki page about a new FBML tag: FB:rock-the-vote. The new tag displays a Rock the Vote widget in your application. Jesse Stay has pointed out the image below which shows the voter registration form that appears when you click the text highlighted within the FB:rock-the-vote tag.

The interesting part about this tag is how sponsors are displayed when you click the link. Would Facebook launch an fb:coca-cola tag? I’ve wondered about this previously and for political purposes this new tag makes a lot of sense. Promotional tags would be an interesting revenue stream for Facebook but it could also lead to more cluttered applications. Imagine if their were widget tags that easily displayed random interactive items.

Do you think this new tag is useful or is this a sell out by Facebook?
