Thanks so much for elaborating. I agree that each point you raised are quite valid, and each of them are drawbacks that PLAY has. 1. Its true that there's a chance that users may delay purchases in order to get discounts, and its a common issue for deals site like Groupon (where instead of going back to the business they wait for other similar deals from the same or other businesses). One reason I feel it'll be less of an issue for us is that we are using points, and these points can be used up now, or accrued to get larger rewards. So if you have 4 points and you need 1 more to get a free cup of coffee from Starbucks, you don't feel the need to wait, because you can always either get another cup of coffee for free later or simply keep the points and save it up for a bigger reward. In case of the graphics card, even if you wait for the 5% discount, the ad has been effective because you are paying attention to that brand and favoring it over others. Its up to the advertiser to not put up deals that would hurt themselves (like offering the graphics card for free). 2. Both tracking cookies and having the user log in are clumsy and deters people from engaging. We are opting to have the user log in, and we're trying to do it in a very elegant way (after the user collects the first point, they are asked to "save" their progress). However, we will experiment with all possible options and see what works the best and provides the least friction. 3. This is another very critical issue we face. To counter this we will have to start out with trusted publishers and advertisers. Basically, the ads would have to be seen on websites where you know they wouldn't put up fraudulent ads or scams. Good design would also play a role, since most scam ads are overtly flashy and are poorly designed. Having said all that, its all based in hunches and gut feelings now. We are building the first prototype and we hope that once we complete that, we can run some test campaigns, to better understand the issues. We know that this platform will have major flaws but we feel that we can also find the solutions for them. The flaws may or may not be the ones you pointed out, and the solutions I presented may or may not work, but we think this idea deserves to be tried and tested. And I personally feel that I can make it successful (otherwise I wouldn't be working on it).
