Ok, I'll bite. I just don't like talking about this sort of thing because it often devolves into scammy ideas. For instance here is a dead simple way to make money if you are really hard up:<p>Build a site where the only goal is to serve ads and get visitors. Give away N of your ad revenue to a random visitor. Write viral hooks into it to propagate it faster. Of course it won't work for long - someone will eventually try to increase their chances by registering thousands of accounts - but while it works you could probably make a ton of cash.<p>Edit: perhaps with his appstore experience he could do this on the iphone - figure out a way to make it cost prohibitive to register thousands of accounts by tying accounts to a phone number?
