To me, honestly, the biggest thing Tumblr has going for itself is the fact that no one uses it.
Originally I was thinking, in terms of "why do I use Tumblr and not other sites?" that the thing going for it is that it's a Post Anonymous Bullshit site. And this is true, and important, but also Tumblr isn't the only Post Anonymous Bullshit site.
I think the key power that Tumblr holds over me is that it's the Post Anonymous Bullshit site that no one uses.
And the reason that's so clutch is because of how much safety it adds. No matter what kind of office or acquaintance small-talk spirals into the direction of social media, which, perhaps in an unthinking moment, causes you to mention you use Tumblr. Even if your conversation partner acts interested in this detail, they won't follow you. Twitter? Tiktok? Fuck man, the person could whip out their phone on the spot and look you up. Tumblr? No way in hell. They'd have to download an app. Make an account. Check it regularly? Just to see you posting "happy fuck him flat friday"? No.
And on the absolute off chance this person does have a Tumblr, and does follow you, well they probably have all the same problems you do that's led them to be active on this site in 2023 so you should be pretty safe in a very girl what are YOU doing at the devil's sacrament kind of way.
