I recently created a post where I added the [AskSN] tag (#758148). However, as it was a question about Nostr, I posted it in the Nostr territory. The other time(s?) I actually posted in AskSN was when I did not find another territory to post. It's kinda like it was my fall-back option. It's good to have fall-back territories (~news, ~lol, ~videos kinda similar in that sense), but they might need specific managing strategies.

As a general comment for most territories, don't expect to become profitable in the near term. Only territories such as ~bitcoin, ~econ, ~lightning seem to have sufficient natural activity to make enough money right now.

My ~science territory is far from being profitable. But it's going in the right direction. I've had it for nearly a year or so. I think you need daily 5-10 posts with decent activity to break even. It takes time and personal commitment. I also generously zap posters in my territory to incentivize them to come back. You probably should aim for providing yourself at least 1 daily high quality AskSN post.

If you want people to donate, you probably need to give them some kind of action plan. Otherwise, they'll think you'll just come back next month with a similar plea.
