You are not alone, you might want to check out @snook video on her feelings. I think communication could have been handled alot better, it might just be coincidence that the smallest accounts ended up being totally blocked from interacting it all but it does seem obvious that they would feel isolated and left out. It's frustrating because I have invested a large proportion of my time into commenting, sharing and upvoting a wide range of accounts, and I now I am left wondering how many I will see posts from again.
