There are lots of cool projects there that I hadn't heard about before.

The upstream news source (nlnet.nl) has the same list of projects, but each list item is expandable with a description (and the project weblink in there).

Thanks for the superior link!

I really need to learn more about Peer Tube. I've heard great things, want to invest the time to avoid streaming problems/costs, etc.

It is pretty damn cool, a good window into it is to browse Blenders peertube community, they use it extensively.

Excuse the total ignorance.

Blender as in the CGI studio and 3D animation blender? Can I safely assume they use it to share and stream Indy and small creations?
