Thanks!

That's where I really need to start at, learning what those are. I know d.tube, but that's about it. Is there a good comprehensive list you know of that I could look at?

I've been thinking about that for the past week. The challenge is typically people won't move unless the user experience is significantly better, or there is something innovative that is key to letting it thrive. Unfortunately, I don't think that many people care about decentralization enough, to commit, although that comes back to your original point of education.
