The explanation for this is that I came from blogging origins. I originally sought to put my poems into modified sentence form as if they were a mutated paragraph. In time I moved to a lyrical format that approximated free form, but still it wasn't quite there. The time wasn't wasted though! Through poems written day after day I learned about rhythm and rhyming. I learned about when the rules should be followed and when they could be broken with poetic license.
Time passed, the poems continued day after day, and the commas and periods dropped away. Now I am writing, when I chose to, in a free form format. I've rose above my stilted beginnings and backed into a more “professional” presentation through repetition of effort. While this may seem to be a surface transition, so much more has been learned. Perhaps it is more than commas and periods, an end only achieved by practice.
