Outside of being great for cross-platform messaging, it's awesome for transferring files. Quick, no restrictions on file extensions, and I've yet to hit a size limit. Great for building an APK and shooting it off to my friends + other devices.

It's also great for piracy. There's a channel I'm in with links to updated Nintendo Switch modpacks as well as one for premium STL files.
