Speaking of checkmarks stripped of all meaning, boy howdy does Tumblr have a deal for you.
I find myself compelled to note that, just like Twitter, these are not in fact blue checkmarks. Tumblr instead has black checkmarks on a blue starburst, while Twitter has white checks on blue. Ah, that’s OK. As Tumblr’s post notes, “Nothing matters! ¯\_(ツ)_/¯”.
