Personally, I don't care whether or not anyone comments my work or not. If they do, then they must really like it, in my opinion. I don't comment on works I don't like and I can imagine that everyone else is the same way. Sometimes I won't comment at all, regardless of how much or little I like it. Only because I feel there's no point some times. I can just as easily PM the author.
Besides, most poetry comments are very low quality--something the mods are trying to eliminate, hence all the recent changes in the Poetry section--so, why would someone post a reply to a poem, knowing good and well that they'll probably just get a warning, infraction or have their post moved, deleted or closed?
The fact that you actually care that much about the lack of comments makes you look pretty selfish in my opinion. If my work doesn't get commented, I just let it be. If one of my good friends here on AO doesn't comment, then I can worry a bit. Only a bit though. Maybe that person's busy or just can't get online at the moment, y'know?
It's not a big deal; you should just keep writing, because if that's what you love to do, why worry about comments? Worry about posting new work.
