When your follower/following count is small and you're getting to know people and build a community of people you otherwise wouldn't meet IRL, it can be a great thing. When you start getting inundated with too much information when you have 10K + followers, it can be overwhelming and you lose the signal within the noise and find that it may start affecting other parts of life. I suppose each person is different, but that burned me out and made me uninterested and I burned it all down. I found I was losing sleep checking my phone and getting unusually addicted to stupid things.
