I'm doing the same thing! To that end, I would be doing a mass unfollowing of people that I regret even following. I only ever care about mutual support, so why care about people who don't care about your work, right?

The Hot pages are a good place to look. Some of the bigger earners here don't care that much about every comment. I don't know if that mentality is what helps them earn a lot or whatever. The term "gone Hollywood" immediately springs to my mind whenever I think of them. Some don't even reply to any comments other than comments of other whales.
