What an intriguing experiment. I'm tempted to follow your lead but value my sanity (and free time) a bit too much. 30 articles in 30 days is about my norm but in 30 different publications without the ability to count a story that gets rejected and submitted to another pub. Whew. That's a lot, but still you tempt me. I'm a maybe at the moment, gonna let this one marinate.
You got me thinking though so I looked back on the last 30 days for me. I published slightly more than 30 stories in 19 different publications. Wowsa that number surprised me. So thanks for the prompting to check that out.
Just for reference for you, in those 30 days I gained 130 followers. I earned $593 but I sold a story outright to Better Humans for $500 so I only made $93 from the partner program.
I really looking forward to following your journey.
