On a practical level, I prefer @pixelfed much, much more than Instagram.
This is because I prefer what Instagram was back in 2012—but with some big improvements.
For one thing, you can put active links in posts. Last I checked, you couldn’t do this on Instagram.
@atomicpoet no, they still don’t let it. is irritating on Instagram (among loads of other irritating features) - “link in bio” 🥴
