1. as soon as it gets enough traffic/attention it will be run over by spammers or other self-promoters. You'd need at least a way to treat some content as more valuable then other. That would require moderators, who need to be vetted, e.g. by reputation. Take a look at 24h worth of http://www.reddit.com/r/all/new/, expect 100 submissions per minute, and try to figure out how you'd managed the submissions from a quality point of view.

3. if news users pay out existing users who are in dept it sounds like a http://en.wikipedia.org/wiki/Ponzi_scheme. If the contract says you have dept but don't need to pay within a certain timeframe then don't be surprised if users signup and never ever pay.

1. I agree with your points but they are not needed for a MVP. Unfortunately I was not thinking that the whole platform would be very similar to Reddit... I need to find some elements of differentiation.

3. Also in this case you are right but I was wondering about a situation where the first users try it with a very small amounts of money (few dollars), they see they are repaid, then word of mouth, more users, more money etc.

3. Still a ponzi scheme. Those are not legal, nor are they something you should be willing to do.

The last users to sign up get screwed. Every time.

Yes... that was actually my concern
