Not secret!

I've ran a 'Free Second Life Linden' site since 2007, and I'm basically going to open one up for BitCoins soon. Where users do things like watch youtube videos/ads, facebook LIKE pages, complete offers, register to sites, etc. and earn BitCoin. In addition to BitCoins users could also withdraw the earned rewards to Second Life, or redeem for amazon gift cards, etc. The site is done, minimum withdrawal is 0.01 BitCoins. I just need to buy/trade for more. Ive traded $L for some, but need more to be on the safe side. On average I'd assume most users would only be able to earn like 0.25 BTC, more only if they put in a lot of effort in 'Tasks'.

Other sites I was thinking about were an online casino where users could compete in skill based games to see who gets the highest amount of points. I'd also like to try my hand at a marketplace.

Those are probably the best three ideas I have. The codes all done from previous projects. Ive had lots of random virtual currency websites over the past few years, so its basically just reworking them for BitCoins and seeing if theres any interest.
