Same here. I have 1980 followers, 110 of them are "dead", and I rarely get more than 60 upvotes. Very strange. Some may be following more than they can curate, but I also suspect there are many who went for a follow-for-follow and can't be bothered to curate at all.
Yeah, I think those are definitely some of the issues lately. Oh well, I guess we already know it's quality over quantity... even on Steemit :-)
