When I'm thunking out beats on a piano or plucking guitar strings or perhaps scribbling stuff on a piece of paper, I call that "doodling." When I'm not really trying to make something good, necessarily, but rather I want to try and see if certain things might work together, I call that doodling. Doodling doodling. Story ideas are doodling. I named this title Tidbits because honestly, my ideas never get anymore than a "tid" more than a "bit."
Have fun reading my random bursts of (probably not) creativity!
