Sadly outside of me, and a few colleagues/friends who actually have heard of Hacker News, I know of nobody who has email through anything other than gmail (and the occasional yahoo or AOL holdout who just has an email address from the 'old days'). I think on HN it's front page news, but those of us who browse here (and even fewer, those who comment and upvote) are a tiny sliver of the Internet. There are a few people who have corporate email addresses that aren't @gmail.com, but probably 30% is through GSuite, and the other 70% is through Office 365 or Exchange.
