Thanks for writing on this Mary. I am generally very quiet aside from what I post, and comments here and there...but I watch, and have been wondering about the "curators"...meaning the auto-curating. Just watching how it works, and the effects it has.
When I find a good post, or at least one I really like, I follow the person to see more. Once every couple weeks I go through everyone I have followed, and take a look over their last few months posts and decide if I actually want to follow them. I find that I un-follow people who post so much that their content is low or has no form of continuity, or people who resteem so much that I cannot find their own posts. (aside from a couple people who only resteem, but I find it all helpful)
There are two people I manually curate, because I really like them and their content...I actually followed them here from youtube. But I really don't understand the massive auto curating. I can see that curators can make alot of SD and SP, but most of the time they are not reading the content.
I am mystified.
I only make one post a day or less, and they can take hours to do...unless I am giving a quick update on a project where people are waiting to see it...
