A few people here mentioned that their online giveaways didn't convert well. You may think, "who wouldn't try out my cool new app for a chance to win an ipad right?" But consider how this may read to your potential new users, "So they want me to enter my information into an unknown service, without any concrete return? and wait, is this one of those... try out any one of these services for a free ipad scams?"

remember that your potential new users have no idea who you are, and people are still generally suspicious of new things on the internet, and rightfully so.
