Nice to hear you done this kind of thing TJ
Some of the slam poets are more literary than others and some of them do more like a stand-up comedy thing. But I guess you know a lot about this. Taylor Mali has become national champion 4 times over the last 8 years. So he definitively is both very good at what he is doing and he knows how to move people and what people wants to hear.
I have no big trouble with the word poetry. You express yourself with words and try to express as much as possible with as few words as possible. If it is entertaining, tells a story or whatevaah, is it less poetry? Well, maybe it is less poetry in a traditional sense. But frankly, I like this much more than over-intellectual word constructions which barely say anything to anyone. Having a strong thought and keeping it simple, is sometimes harder than complicated words constructions. So yes, I think it can be a form of poetry. If it is entertaining, it doesn't make it less. Anyway, many things through out history have been labelled or called "poetry" and I don't see any point in trying to narrow this "word". Its like the term "qigong". Almost anything can be called qigong, even writing a poem.
Well, poetry or not, I still like very much what Mali does.
