It's already started a little, but over the next day or so, the internet will be filled with jokes, pranks, fake "announcements" from companies, fun interactive activities, games, and so on. A lot of these can be quite clever and interesting so I think posting about them in general is fine, but in the interest of preventing them from completely taking over Tildes, let's try to keep as many of them restricted to this thread as possible. Ideally, a separate top-level comment for each individual item would be good.
If something particularly discussion-worthy comes up (like an ARG or activity that a lot of people want to talk about), a separate thread is reasonable, but please make sure it has the "april fools day" tag. That way, if anyone wants to avoid seeing the April Fools' Day threads, they can use the topic tag filters and filter that tag out.
I'm going to use the "official" styling for this topic (that's usually only for ~tildes.official topics) to make it stand out more to try to encourage people to notice it. My availability tomorrow will probably be limited, so if you notice people making individual topics for April Fools' Day things that don't really warrant their own topic, please (nicely) encourage them to delete and post in here instead.
