Valentino Rossi

Sure, we said this list was in no particular order, but who else would be at the top spot? The Doctor adopted social media only recently but has been fairly active ever since. Known for being a master on the track, Vale has also managed to keep his private life just that. Through Twitter, his fans now have closer access to his life outside the track than ever before. Granted, he doesn’t interact with his fans nearly as much as some of the other names on this list, but Rossi will always be a fan favorite. As such, any chance he gives to peek inside his life and get to know Valentino, the man, is a welcome one. There’s just one caveat: he tweets mostly in Italian.
