I think if you want to call something a “———— heritage post” then it needs to be from like, a bygone era of [tumblr]. it can’t be a heritage post if it’s from a year ago
i think the eras of [tumblr] are fairly vague but can pretty much be defined as:
2007–2010 [tumblr]; a mostly unused site. boring.
2010–2014 [tumblr]; fourth biggest social media platform in the world. fandom vs hipster. denny’s. mostly high school/college aged users. most like modern tiktok.
2014–2018 [tumblr]; yahoo acquisition and dashcon killed new user intake. everything became cringe, the vibe changed drastically. most like modern twitter.
2018–2022 [tumblr]; porn ban happened. roughly half the userbase vanished overnight. suddenly a much more insular community of late-20 somethings. most like modern… google plus?
2022–2026 [tumblr]; present day. wordpress started making rapid changes, the porn ban was relaxed, twitter migration started to some extent. life is happy.
2026–2030 [tumblr]; posts removed in favour of tumblr live, no real moderation (outlawing of machine learning), site becomes almost all pornography and shock videos. most like modern 4chan.
2030– [tumblr]; final act of president jess biden is to take the site offline after the string of assassinations it caused. users migrate to tin can on a string dot gov. most like an episode of seinfeld
