Really enjoying this running experiment you have going on. I think you’re right about the size of your readership having an impact on some of the results, but I find it all very interesting. And encouraging!
I’m curious now about what size of readership you have to have to start to go on your own more and more? I suspect it will always be a healthy mixture between your own publications and those of others. But the larger your readership the less you need larger publications simply to be seen, but more to continue to grow your readership and sustain your authority as a writer in a certain niche.
Food for thought!
