The 2010 Fields Medalists have just been announced! The moment I found their names on Twitter, they were already on the Wikipedia article. Go figure.
I am not familiar with any of their names, except that Ngô Bảo Châu’s name was tossed around on the blogosphere awhile back because of his proof of the fundamental lemma.
Annoying Precision 
I sheepishly admit to being rather disappointed that all the Wikipedia articles had already been updated by the time I got to them…
