Something I noticed this week for the first time is the date on profiles changed from x days ago to the specific date a user's account was created. It's also now a link to the frontpage on that day.
We just did that. It seems like a neat way to tell people about https://news.ycombinator.com/front, plus it's amusing to look at how HN was on someone's 'birthday'.
We also made older timestamps say "May 4, 2009" instead of "3124 days ago".
