A) Witness Question - I might have missed it, but why is there a limit on the number of witnesses? In other cryptos, everyone has the opportunity to mine, or be a witness in Steemit's case.

I'm new to this site, so perhaps there's a technical reason, but I think everyone should be able to witness/mine and develop a daily stake for playing their part, instead of a select few out of hundreds of thousands.

B) This was a mesmerizingly awesome and through post. It educated me a lot of the background and backbone of Steemit. Thank you for this upgrade of my understanding of this platform and community.
