Facebook is MySpace, Tumblr is live journal, reddit are forums and Discord is Skype.
It's all been done. Why create the new when you could recreate the old?
But yes; I to crave something new.
Can you think of anything new?
The "ideal" of Mastodon was the first thing I regarded as new. This idea to properly own your communities and conversations and move them around and connect/remove others as you would an email address was novel.
In reality, it's nowhere near that ideal. But I still want to see if anyone over the years could make it work.

Much less realistically (somehow), I'm still waiting for that moment where we run a full on AAA game in the native browser. I think the tech is now at the point where it exists and is possible. Just not the incentives. But IDK if that's the "new" you were talking about.
