Currently hosting a Sweepstakes at http://daily.opineer.com The prizes are: 1 Beats Pill 2.0 Speaker with Dude Character Stand or an Amazon $250 Gift Card 4 Magicbox Portable Wireless Speakers or Amazon $30 Gift Cards Are the prizes enough to grab attention or are they too little? I'd love to hear your experience with sweepstakes or giveaway events.
I'd be really dubious about the prizes ever getting awarded. You have 446 likes, you have no contact details aside from email. If you did gift cards you could open this up to a broader audience - then again you may do better focussing on local issues like obamacare.
I didn't notice the prize at first. I would make it more prominent. One way you can help give some credibility is to have a testimonial from a previous winner under or near the prize offer. Something as simple as "Thanks for the speaker! - John Doe" would help a lot.
