Writing muscle

This is an opinion I’m asking of you, the people that read my blog (for which I am very, very thankful). What would you think if I post a prompt every week? A prompt that helps you with your writing muscle and a few days later I post what I made of this, and you are encouraged to post your pieces as well?

This will sharpen our writing muscle together and gives us incentive to write more?

What do you think?
