Never having considered that sound has any value, they won't be used to listening or to reading out loud. They present watered-down versions of the mass culture items with which poetry competes. But such poems are less interesting than those things. But because it's the least like poetry that it can be, it loses the readers who are looking for that which is specific to poetry. What's interesting about poetry is the ways in which it's not like other forms of writing.
Poetry is accessible.
It just requires throwing yourself into it and becoming engaged with it as a complex, developed art form that's quite sophisticated. Right, that's the whole idea of poetry in the late twentieth century. Poetry is an activity that allows us to interrogate language and meaning. People can and will get very excited about poetry at its most complex, at its most difficult, and about the ways that it's most unlike other kinds of reading, because you can get language and acoustic experiences that you can't get from other modes of writing. It's those things that ultimately attract the die-hard poetry audience, which is very intense and very committed.
