Weekly roundup: a short Pomodoro presentation

Here is my Pomodoro Technique short presentation held at phpDay 2011 in Verona. It's not the same as the full one at PHP Barcelona, but it contains some frequently asked questions about Pomodoros along with some handy tricks.
Remember that English is not my native language. :)
