Replying to Getting paid using Gigwalk

So one of my friends showed me this iPhone App called Gigwalk. From what it seems you get paid to go to a business and usually take pictures using a Microsoft App, and take a short survey. You submit your pictures and I'm pretty sure Bing uses them when people go online and look up the business. Most gigs are about $5 but some get up to around $80. There's quite a few in my town that I want to do, but just haven't gotten around to doing them. Anybody have any experience with the app?
