I get a lot of questions like this, asking what specific topics Medium is looking for in Boost Nomination Pilot publications.

I'm going to ask you to shift your thinking, though. It's not what topics are we looking for, but more that we're looking for publications run by editors who are subject matter expertise in their niche topic.

This expertise can mean professionals or academics, but it can also mean folks who have unique lived experiences with their topic. The key is that the editor is someone who is uniquely well suited to understanding their topic.

For instance, we'd be more likely to let in a publication dedicated to Midwest gardening run by an editor who'd been hobbyist gardener for 20 years than I would be to let in a tech news pub run by a marketing content generalist.

The key here is that we don't want folks running pubs based on topics they think people want to read about -- we want folks running pubs focused on topics that they have unique, specific experience with.

So, I think it would be useful to flip your approach here. This isn't about filling gaps to produce certain kinds of content. This is about identifying the kinds of content you are uniquely well suited to be a leader on. It's about author/editor experience and passion.
