A lot of social media sites will try to get you to sign up to save/bookmark posts on-site or in-app (even Lemmy!), but if you’re viewing them via browser you can just save a bookmark to your browser.

The perks to this are: you don’t necessarily need to make more accounts, your browser bookmarks can be renamed & tagged & organized into different folders, and you can search your bookmarks!

A lot of on-site/in-app bookmarking doesn’t provide those benefits, at least not without trying to make you pay up.
