Like most of you, when I joined the site, I thought that "Steem" was a different way of saying "Steam" - like the stuff that comes off a hot cup of coffee, or boiling pot of water. It turns out it is not. When I watched the video interview that @dollarvigilante (The Dollar Vigilante) did with @dan and @ned, I found out that "Steem" is actually short for "Esteem". Very cool!
If you haven't watched it yet, you can watch the whole interview here.
The definition of esteem (from Google) is "respect and admiration, typically for a person". What a great word to use as the foundation for the site/coin/community!
