"nothing lasts, nothing is finished, and nothing is perfect" -- http://en.wikipedia.org/wiki/Wabi-sabi

What WabiSabi is

clean

Any feature that involves complex logic is right out.

concise

It is the author's opinion that sprawling code is as bad as obfuscated code.

useful

That said, minimalism for the sake of it doesn't help anyone. There should be a balance.

What WabiSabi isn't

complete

Other WikiEngines include everything and the kitchen sink, not to mention an atoll or two plus a coral reef. That makes them harder to understand and use for anyone who doesn't need the extra features.

definitive

These goals are likely to change over time and there's nothing wrong with that.
