“Tags work a little differently than hashtags do on platforms like Instagram and X (formerly Twitter). When composing a Threads post, you start a tag by tapping the # symbol and then typing out your topic. But instead of being limited to just one word, you can type out a whole phrase (with spaces!) and add special characters, according to Mosseri. However, you can only make one tag per post.”
I wonder how the tags will work if they federate with ActivityPub.
So the Tumblr tags will finally reach their true form.
I’ve never really used Tumblr but it does sound like a cool fix, hope other Fediverse platform may consider it in the future.
