All of your questions have been answered in other articles about EOS here on Steemit. Just check the EOS trending page. Parallel processing is thoroughly explained in some of Dan's posts.
BTW, if Steemit was running on Ethereum, you'd have to pay with Gas every time you upvoted a post, AFAIK. This is just one of the reasons I think EOS is going to supersede Ethereum.
I am sure for every question anyone has there is an answer on the internet ad/or here on steem. The point is i haven't found it yet and i am not going through a long list of articles hoping i find the answer somewhere. Isn't answering questions like these the whole point of replying to comments?
Sure, answering questions is one point of replying. But would you rather rely on the information provided by a random person on the internet, or the actual programmer creating the project? I'm pointing you in the right direction to get the information you want. Read the articles by Dan Larimer on EOS. Or check out the EOS presentation he gave at Consensus on Yoitube. He does a much better job of explaining it than I could ever do.
Alright i get your point, thank you
