@timcliff is Witness #4 out of 135 witnesses. He's one of the top 20 who makes decisions for the platform and keeps it running every day. He is also a large shareholder (whale) in the company and is, for all intents and purposes, a King of Steem. He recently retired from his day job in management for a medium-large sized tech company so he could devote more time to steemit. One of his recent projects is developing code for a hard fork (which is another way of saying he wants to introduce new ideas to the owners of the company and push to have it implemented to make the platform a better place. As a top shareholder, and ample experience in coding, he believes he has influence to do so, and thinks hard forks should not just be up to the core steemit development team anymore, but that people like him should be allowed to propose ideas as well).
@sircork is also a witness. He has helped to make MSP Waves (a steemit broadcasting service) what it is today. Although he no longer works for that organization, he is constantly doing things to not only strengthen the platform (he donates SP to good causes, he has a charity based in steem, and he curates and supports other minnows), he also is a rabble rouser. He has a big mouth, and everyone knows it. He likes to call out higher ups when he thinks they're either taking advantage of the system or not doing what he believes they should be to make this economy healthier. This includes everyone in the top 20. They know he feels this way. And this is why the debate should be very interesting. He's very knowledgeable on blockchain technology and has no problem holding his own. He is a leader in ideology and a major influence in how the masses are beginning to question how things are being run. He is also, for all intents and purposes, a King of Steem.
So we'll have debates among top witnesses in the future, and the title of the segment indicates as such. It should be very educational for you. Some of it may be over your head, and that's completely OK. The main thing is you'll get to hear what makes this place tick. It should be a very important debate as they disagree on some important things, and this is unprecedented in approach as it is live.
