It is a lot, but we do not really have spam problems here for now apart from a few rare exception who cannot take a hint ;) Downvotes keep them in check.
I do the #FollowFriday posts to try and help people gain followers. I can find plenty of good stuff in my feed every day. There's a pretty good variety of posts out there.
I do check out you and other peep's Resteems on my feed.
I simply don't have enough time of the day to consume everything.
Time is the limiting factor for me too. I can only read a selection of posts each day.
