The part where you assign a value of quality to "reddit".
Would you had visited the website, you'd known that due to its number of users and (this is important) many subreddits, assigning a value to "reddit" instead of a specific subreddit is akin to assign a value to "the internet" when in reality you meant to degrade a specific forum/website.
I've been reading reddit for approximately 7 years, and I have multiple accounts on reddit that are in the 6 year club. I don't understand why you would assume that I don't read reddit based on the comment.
My assumption was that the original person I was replying to came to ycombinator from /r/programming. That is a good example of a subreddit where a vast majority of comments, even generally upvoted ones, are low quality. For a tech related subreddit that has higher quality comments, /r/netsec is maybe the best reddit has to offer.
