Great explanation of Steem success and popularity @reko.
Happy to see the steem blockchain & Steemit success by having huge traffic that is shown in alexa and the number of transactions happening every day and on a weekly basis. People do more transactions via steem blockchain because It costs nothing and also doesn't take a couple of days for transactions like bitcoin.
I had written an article about this two weeks ago. It might help your readers. I defined the reason why steem blockchain is growing so fast.
