That's a tricky question considering very few people know how it actually works.
It's like driving a car.
How many people actually know how the car works?
Most only know how to drive the car, at best.

It's difficult to know which direction to point you in when it's unclear how much you already understand.
Like knowing the differences between POW and DPOS consensus.
Are you actually interested in renting a server, installing/running the software,
and then trying to get people on Hive to vote for you?
Or do you just have generic questions about how nodes work?
Those are two very different things.
