John Ousterhout [0], Raft's co-inventor, did a user study (to hammer home the point that raft is easier to understand than paxos), and those presentations, presumably filmed to explain the two protocols to the users part of the study, are up on YouTube.

Then there's this presentation-animation, too, which I find to be pretty nifty: http://thesecretlivesofdata.com/raft/
I really enjoyed the presentation.
And yeah wow, Raft is dead simple.
Yes, Ben Johnson's (https://github.com/benbjohnson) presentation on Raft is great. He is also the creator of BoltDB (https://github.com/boltdb/bolt) which is a core component of Hashiscorp's Raft implementation (https://github.com/hashicorp/raft).
