I do it, I use run-on sentences.

The intent is to convey. Sometimes you want to take half an idea and get it going, and then fire off its rockets and send it into the sky.

The run-on sentence is a tool to be used, like any other. But you have to use it with care, so that the reader knows you know the difference, and knows that you're not just plain illiterate.

You might even want to point it out explicitly.
