I have a personal pub that is poetry based. It's called Fiddleheads & Floss Poetry if you'd like to see how I have it set up. I BARELY know how to do the pub set up stuff enough to get by and make it look nice.
Anything you want to write consistently in is a good idea for a pub. Or you can find 2-3 major go-to pubs for that particular content.
Biggest advice---PROMOTE IT.
The letters feature is great for getting the word out to your readers when you have posted new content.
