Haha, maybe there are some tools where you can make a movie on a piano!
But that's the point: most people don't realize they are being funneled into this limited expression. They don't have access to the web-equivalent of a piano or a movie making tool, to let them author web content, hypermedia, as a first class citizen.
Not just limited tweets, posts, etc. It could be so much richer, and yet it's not. Don't you think that's strange, and strange that everybody adopts it?
Those tools, FB, Twitter, etc -- it's just not a creative free expression. But it could be!
It probably sounded like I was dissing the very creative tools you listed. I wasn't! Not at all. I'm a big fan of processing, check it out, these are my sketches from 13 years ago, even back to the days of Java: https://openprocessing.org/user/15252 -- and here's some videos of some of them: https://www.youtube.com/@TheCrisfolio
The point is not that there are no tools for creativity, it's that the biggest tools for expression for most people are not that creative. They restrict the authoring of hypermedia as a first class citizen. Self-evident limitations, right? Like you say. But what's not obvious to most people is how limited those companies actually make them, and yet how much that could be opened up.
So we get the bland commons. We think we're being so creative -- we are in a way -- but we're also not. Is that just people or is it a lack of tech? You know what I'm saying? Or you don't really get it?
