Some of the questions have ambiguous answers - like what does PoW do?

Nice domain name and nice idea. Just would be better if it does not mess up with fuzzy things like "to solve a complex hashing puzzle"… It is much more comprehensive than that. Just needs some attention and time. Someone can hopefully describe it in simple terms (in plain English or whatever their native language is).
Have a look at http://emn178.github.io/online-tools/sha256.html and write there letters "PTN" where P stands for the previous block hash, T is transactions and N is a nonce (correct me if anything is missing). Now a simple visual "miner" simulation can be done which looks cool and helps everyone understand how it works. Is there anything similar already?
