HN is absolutely not the most popular tech forum in the world (most stories struggle to get half a thousand votes, and the actual rate of access for HN is so low that dang is alarmed when he sees more than sixty logged-in queries a second[0]), and reddit just reposts what's on HN.

You're conflating "I read this" with "The world reads this." This is a common error. The trick is to realize that your experience with the internet is not universal, and that it is unlikely you are the average user in any group you're in.

Further, it doesn't even show up on the subreddit you mention very often; I just checked the reddit BigQuery database and FORTH posts don't collect a portion of upvotes worth mentioning in any given year.

Also: Using superfluous question marks for emphasis is a reddit habit. It should not be done on HN, because it is annoying and lowers the quality of discussion; the guidelines forbid uppercase-emphasis for this reason, and this is more egregious.
