I’m sure plenty of Bluesky power users will read this and say, “Who cares. I’m happy with a tiny site that feels like a memory of how I used to use the internet.” Fair enough. But one day you’ll be the last person writing words on the web and wonder where everyone went.

You can easily replace Bluesky with Mastodon, Threads, Facebook, Instagram, LinkedIn, YouTube, Medium, Blogger, Reddit, Twitter, and TikTok.
