at the moment, ranking is still sats based. So the posts with the most sats invested in the last four hours tend to be the posts that dominate the front page and get the most visibility.

I find that if I take the time to write something and want to make sure that people read it, it's usually worth a boost of 500 or 1000 sats to get it on the front page. That number has been increasing though, which is maybe a good sign?
