Okay, here's what I've got:
Good writing fulfills its purpose with clarity, vivid detail and self-expression. That purpose can be anything from teaching someone how to use a software package to analyzing literary text to exploring the dynamics of interpersonal relationships.
Good writing uses language like a paint brush, evoking images and feelings that are clear and impact the reader. It hits a true emotional place that weak writing just can’t seem to reach.
There is a rhythm and meter to good writing much like there is a good beat in music. Good writing sounds like music when read aloud. It can be melodic or a staccato drum beat, but it’s still musical.
Good writing is compelling. It entices the reader and leaves them hungry for more. Characters are like ghosts who cling to your memories and won’t let go. Finishing a good book is like saying good-bye to a dear friend.
