yes that's how it is, i have 800+ and most of the times my upvotes are between 20-100 and you can image then comments i get too :P I can understand that some people don't have the time to comment or even read most of our posts but the majority of our followers are, bots,dead accounts and just people who follow everyone expecting the same :P
My tactic is to check my feed, read the whole post or most of it upvote it and try to build relationships with the people i follow
