I think it's simple in the "simple made easy" kind of way that Rich Hickey has spoken about [1]. I think something can be deep, refined, and simple. I'd also say that those are my favorite concepts. I guess it's what I think of when I use the word 'elegant'.
It's really clean and straight-forward to use, but the simple components provide a lot of flexibility and power, while being easy to teach someone.
I use trello for just about everything, and I would have dropped it a long time ago if it took more than five minutes to show someone how to use the fundamental concepts. I can get them up and running in no time, and the users (even non technical users) tend to find all the interesting bits on their own as they go.
