FWIW, I do note the usernames comments come from sometimes, particularly if they're insightful.
Regarding the numbers here, I'd say there are multiple thousands, possibly 5 figures. The top article about Apple refusing to publicly backdoor the iPhone (https://news.ycombinator.com/item?id=11116274) got 5667 points. And sometimes my comments will attract a reply chain but not get upvoted, which shows that some proportion of people doesn't upvote here.
