A UX risk is that the prominent photos, as in your mockup, draw the eye and activate a visual mode of thought with specific concrete images. Appreciation of poetry also tries to trigger visual thoughts, but through words and imagination/ambiguity instead. So the concrete visuals might interfere with literary appreciation. (Consider also: often the most-appreciated text appears bare on a plain page.)

This is just a hunch, and you could perhaps test an imagery-heavy look against a spartan text-centric presentation, and see which draws more of the exact kinds of reading/engagement you want.

I read the domain first as "po"-"three", and thought of Edgar Allen Poe, but with a little thought can see it as "po"-"eh"-"three". As that, it is effectively short and memorable... I think it could work well.

Good luck!
