Athens.
Tonight I'm at the opening session for WebSci '09, and we're looking forward to a keynote by Sir Tim Berners-Lee, on the twentieth anniversary of his invention of the World Wide Web. The conference itself is going to be opened in the presence of none other than the president of Greece, though, so the place is swarming with Greek police (unsurprisingly, given the continuing low-level unrest in the country). In fact, there's a couple of secret service agents coming through right now, earpiece and all. His Excellency himself is running fashionably late.
