This one isn't even live yet, but it has a website and, if it comes to fruition, would be one I'd support.

Bringing clarity to emerging technologies for the layman is their declared aim (although not in those precise words) it's a news site for blockchain, crypto and other emerging tech like AI, robotics and sustainability. It will help new technologies promote themselves and, has a token that will facilitate this.
I'll be doing more of these, so if you have one you think is good, let me know.
