This is a great TED talk - Matt Cutts speaks clearly, it's a good length (and you can follow the interactive transcript if you need to, although I suggest you try the first listening without the transcript) - and it might even inspire you to try something new for 30 days as well. How about trying to use one new English word a day for 30 days?
My own 30-day challenge: I'm trying to get up when my alarm clock rings the first time, and not press snooze. It's going to be tough.
When you've listened try the vocabulary review exercise to practise some of the phrasal verbs and idioms from the talk.
My blog has changed! If you're looking for my English-practice exercises, they're all still here, just look in the archives.
