I do have a list of favorite authors on Hive from which I generally read (or listen) to their content. I don't always write a comment unfortunately, but in a high percentage of cases I upvote posts I read if they are within the 24 hours limit (and they deserve it, in my opinion).
Besides that, I am constantly looking for posts that may be of interest for my Hive news roundup. That's between 20 and 40 posts every week, most regularly between 25 and 30. Of course, I check out many more posts to narrow them down to those numbers. They are often in addition to the ones from my favorite authors.
Like you, given that I need to go through so many posts, I have formed a "defense" mechanism. The title plays an important role. When I look for news, if I don't understand from the title what the post is about, I just skip ahead. I noticed some interesting posts as actifit posts (not related to physical activity). But I will never look for news and rarely check the content of an actifit post, unless it's from Actifit itself or its creator. I feel the same way about any kind of bulk content, where several types of unrelated content types and information is presented in a bulk instead of separately. They seem hard to follow, and reduce the chances of people interested in any of them to read through.
