I am sharing as much as I can find on my VA Twitter (but also other stuff) - the great thing about Steemit is that shared on Twitter it comes with a image and short description.
Myself, I am just in the process of installing Twitter Cards on my artists pages.
About our artists on Steemit: unfortunately the ones I listed long ago here, most are not active:
