so... what are your metrics for what you will comment on. when I go out browsing steem posts, it takes a lot of time to find particular kind of posts that I'm looking for, and often, even if it's an interesting post with content that I wanted to read, I just don't have anything to say.
I'd be interested to know a bit more about your methodology.
As to metrics for what I will comment on, you can read this passage from my advanced commenting guide.
When you don't have anything to say... think outside the box.
Heck once I wrote a short story on a post I didnt know what to say about and got a $7 upvote on it.
