It's been another big week of rankings, as the drivers make their last minute preparations for the 2012 season. Most are in Melbourne, or are on their way, and there has been talk of flights, of food, and of acclimatising to the surroundings. We've got a new member of Twitter, with Fernando Alonso making his debut on the microblogging tool, whilst Kimi Räikkönen appeared on Top Gear and proved himself to be more than just the monosyllabic Iceman we know. Also on TV this week, Lewis Hamilton made a few appearances in his brother's documentary, and it was great to see him helping Nic out when analysing some footage. Roll on next week when we'll have seen our guys out on track for the first race of the year.

Movements for Week 4

• +2 Heikki Kovalainen: More Heikki and Catherine cuteness!
• +1 Pastor Maldonado: The Williams team have been getting involved with a Japan tsunami charity.
• +1 Bruno Senna: The Williams team have been getting involved with a Japan tsunami charity.
• +2 Felipe Massa: There's nothing like spooking a TV presenter, especially when you're driving on snow!
• +1 Daniel Ricciardo: Getting all excited down under in Melbourne.
• +4 Lewis Hamilton: Some of the scenes of Lewis helping out his little brother in the Nic Hamilton documentary were excellent.
• +2 Jenson Button: Cheering his girlfriend on as she completes her first marathon: "Congratulations @jessybondgirl! girl did great!! 4hrs36mins pretty good for her first attempt. Time to stuff our face with some good food!!"
• +2 Timo Glock: Bringing back his video updates, the first from Melbourne - on a bike!
• +1 Heikki Kovalainen: The man does love to be at one with nature. We've seen his bird-saving antics, now he has a new friend!
• +6 Fernando Alonso: For not just joining Twitter (@alo_oficial), but for doing it in style with a rather fab and cute video! Yes, it is sideways. What of it?
• +1 Jenson Button: Not only does he cheer his girlfriend on, he gets told off by the police doing so!
• +1 Narain Karthikeyan: Sharing some pitlane pictures is always good - the garages, and a car!
• +10 Kimi Räikkönen: The Iceman made his much anticipated appearance on Top Gear this weekend. Points for being just as confused by the Lotus thing as the rest of us, for liking to sleep even before a race, for going super fast and not even appearing to try, for wanting the Stig's job, and for generally being more smiley than we've seen in a while.
