I don't think it is a political event, except in the broad sense that Wikipedia itself is "political" in terms of being a statement that every thoughtful and kind individual has a fundamental human right to participate in the creation of knowledge...I doubt very much if this event alone will bring about any positive changes in Egypt or anywhere else. But I am certain that Wikipedia itself is already making positive changes all over the world, and this event supports Wikipedia.
A little bird told me that Jimmy's been focusing a lot more lately on Wikia (his wiki business) and less on Wikipedia. Fine. But look at all the minefields he can diffuse! His ceaseless positive vibes have guided wikipedia through many a rough passage.
