I was actually just thinking the same thing. Especially in the photography section, which I mostly follow there is a huge amount of low quality photos, or even worse, stolen work, which is very off putting. Once you find talented authors with content you like, you kind of stay in that circle. I can imagine it is very similar in the blog section:)
It's a pain in the ass to try and weed out the genuine content from the ripped one, and I'm very anal about that. I really like my circle but it wouldn't hurt to add more people to it, keep it fresh and more diverse.
edit: added you on the circle, though I give a little more sparingly to posts with only one photo, I want more!
Glad to be in your circle, I am not much of a writer but I’ll do my best:)
