I've got this idea for a toy social media network that costs ~$1 per byte to post. No advertisements. It would be like an experiment in how dense people could make posts. If you wanted to post an animation, you would post a javascript file like dwitter.net
Instead of having "upvotes" or "reactions", this function would be the same as replying a single char or two. If multiple people post the same thing (like "" ":)" "L"), it gets collated and boosted as a single message.
If you want to flex, you can drop $10,000 to post a 10kiB picture of your dog. Or spend $1000 to write an overly long post. But I imagine long posts would be seen as bougie.
