Demonstrations inspired by Occupy Wall Street spread worldwide today, with marches across the U.S and Asia. According to Reuters, most large cities in Europe saw protests, with tens of thousands in Rome and London. Here in Pittsburgh, a column of marchers, chanting slogans and songs, snaked through downtown to gather at Market Square; organizers expect 1000-3000 to gather peacefully in the city center this afternoon. Reuters is liveblogging events in other capitals.
