well written, good information. I recently posted a reply to someone who was complaining about the slow transaction fees, I asked him for the tx id, and what will i do with it, turns out they had no idea of the existance of the ledger and blockchain.info. I showed the details and the low fee they opted to pay. I didn't get as little as an upvote for providing some insight, but just more complaints about the fees in general. I am definately upvoting people with good information.
