My reply was to tumutanzi. I remembered him posting about it the other day so I looked through his post but couldn't find it. So I googled, "tumutanzi @ned 500,000 steem" and it turns out the reason I couldn't find the post is because he's replace all the the English with Chinese.

Here's the post in question though:
