Great idea! Some request

* add an API (apps, mobile browsing)

* integrate tipping (upvote = tip)

* add signup fee to limit spam

Not sure if upvote = tips is a fantastic idea or a way for trolls and dramatic people to make a living.

Instead of paying trolls, monetizing trolls might be a good idea. You could have people buy karma, buy mod rights, buy out other people's mod rights, etc.

Of course posting and downvoting would have a karma cost.

Talk about a "knowledge economy"!

> add signup fee to limit spam

- this assumes that there would flood of users on this site and a chunk of them will actually pay for it. Will you use HN if there is a fee? Instead, why not just write an algorithm to limit spam Or a 'report spam' button?
