I've been mulling the same. I think the biggest "competitor" at the moment is ~charts. Which, charges 210, w/ a trust-based stimulus program overlay.

I'm also mulling a stimulus program too. Eg. "Best post to ~econ, with a chart, every week, gets 50% of the the next week's earnings." ...and then increase the posting cost to 1K. At some point, I'd be basically, straight up paying for content to get posted.

...then I zoom out, and remember, we're dealing with pennies worth of BTC on each of these things. It's almost not worth our time for any of this, with these levels of SN users. It would be easier to just give a fixed amount of sats, rather than trying to do the accounting on earnings without the tools + API necessary to automate.
