Your questions are not annoying at all.<p>For moderation, I implemented a point system, just like Hacker News. Users can vote replies and topics up and down by one point. Once a reply goes below -5, it gets collapsed (like Digg). If a user has a lot of negative points, they get warned or banned.<p>I also thought about giving the topic creator extra tools to moderate but I see that as an "I'll fix it when I have it" problem right now. A similar solution could give users with (for example) 5000+ total points moderation power.<p>The point system has a lot of potential as an incentive system. For example, would be great to gives users an "on-fire" badge if they have been very active over the last few days and their content has been highly rated.<p>If the unthinkable happens and this takes off, I'd see my advantages two-fold. I'd be the first person in that space and I put a lot of focus on simplicity and execution. It's very easy to copy things, especially simple concepts like a public message board. It's very hard to create a engaging user experience, even if you copy. Not sure if that helps if somebody decides to get in this space with millions of dollars in their pockets, but that's probably always the case, no matter what you do.
