Using Facebook like for Voting Mechanism

It’s now Easier to Administer Promotions on Facebook

Now, promotions may be administered on Page Timelines and in apps on Facebook. For example, businesses can now:
  • Collect entries by having users post on the Page or comment/like a Page post
  • Collect entries by having users message the Page
  • Utilize likes as a voting mechanism
As before, however, businesses cannot administer promotions on personal Timelines.

Good move. We can use this like feature, for administering the promotions.
