I'm not sure I understand the need to analyze but I suppose if I needed to be more specific, I like sharing my poetry with people who read poetry and hopefully it will mean something to them. I also have pieces (not all of them) that I want to hone and submit to various places. Not everything, but some pieces. Yes, I have pleasure from it or I mean, I wouldn't sit here and do something almost daily that was painful. You did say "who" do we write for and so I guess I didn't answer that directly I meant, I don't "write" for anyone in specific. I just put it out there. There's no way I'm going to try to write for the world of the Internet. That would be both insane and quite impossible. At least I think it would.
I also enjoy eating more when I'm with someone, although a few fast food places would probably tend to disagree with that.

I'm sure there are people who write for a lover, a friend, or someone like that. Maybe that is what you mean. I don't know. I don't write for anyone person. I don't have the energy for that and one reason is that would mean I'd have to please them and after decades of caring and serving others, I've paid my dues there. That isn't to confuse a workshopping poem with pleasing the person who offered critique. That's an entire different animal but then seasoned poets already understand that. Just to write for another, no, I don'[t have anyone like that and I guess if I did I would say "to so and so" but there isn't anyone. sad me.
Sure,
but why do you post?
I'm seeing how that statement could come off in the wrong way.
Let me rephrase:
If writing a poem is a completely self-fulfilling act, what's the motivation for making the writing public?
I eat for pleasure, but it would be weird to regularly post video of my mealtimes, yes?
