Just noticed PIXELS are looking for bloggers who write about art, photography, and the “online art business.” They say “ We’ll just publish the title of the article and a short summary (one paragraph or less).” So, you could link your art- related Medium articles through them to get more readers.

“If our readers are intrigued by your title / summary and are interested in reading the entire article, they can click on a link which takes them directly to the article on your website.”

PS, I’m not affiliated with them in any way. It looks like a good plan if you write the type of stories they want.
