It amazing how quickly the company seems to have developed into something with a recognition beyond the development community. I first cam across it a few years ago while working in England, and that could not have been too long after its launch. What struck me about it at the time, and this has been said more succinctly elsewhere, is how simple and elegant it was to work with - this was confirmed when even the thickest of non-techies in the office could work it out in less than a couple of minutes. Reading the comments here seems to verify my initial thoughts.

I have heard it said before that some of the best ideas are those that take complicated things and make them simple or easily understandable, and their success goes a long way to proving that point.
