I think we can say that blogging has been a boon for the essay form. It follows that micro-blogging could be a boon to poetic forms. If we're going to posit a bronze age for poetry, though, I think we'd have to also leave a lot of room for giving credit to the poetry slam movement, which of course has its roots in rapping over beats.

i rap over beats.
boats
i blog about meats and coats.
slam on your god damn, dan .. u r the man.
i was actually talking about instant bronzing as in fake tans
i did not mean to confuse.

Interesting thoughts .. to do slam poetry seems like one really has to try to do some poetry. One is going all in with such an endeavor. When people "try" something like poetry performance the effort will often mess with their head and the poetry result just might be terrible. No offense people. And full article blogging is too difficult for most to pull off (including myself). Folks that are micro-blogging alot tend to loosen up and think less and are restricted in length so there is not enough rope for a hanging. These conditions lead to an overabundance of beautiful poetry.
