If you like poetry, than comment on the poetry. If I find your comments interesting, I'll comment back on yours. Hell, I'll look over yours anyway. But don't think that just because we both like poetry, that that entitles either of us to something. It's a mad interest, if I see something akin to my own madness in yours, I'll certainly respond in kind.

, lets collaborate, lets compare)
