I just spent an instructive few minutes trying to find people whose own websites are higher up Google's results than their Wikipedia entry. Jim Carrey has a very new website, but no; IMDB, fan pages and Wikipedia are all higher up the Google results. Sergei and Larry you'd have thought might have made exceptions for themselves, but again no. Barack Obama, Jerry Yang, Vladimir Putin, Mike Arrington, Bruce Lee, Silvio Berlusconi, Rupert Murdoch...no, no, no, no, no, no and no.
In fact, the only person I could find whose website comes ahead of their own Wikipedia entry was the Queen. (The website of her son and heir Prince Charles is beaten into fourth place not just by his own Wikipedia entry but by multiple listings for the West End cinema which shares his name.) Oh, and porn actress Jenna Jameson (link is safe, sorry). It works for me too, but that's only because I'm not famous enough to have a Wikipedia entry (I've never been able to tell whether the one I did have was deleted on reasonable enough grounds of non-notability or because it was composed entirely of lies by my friends claiming I was a spy for the Bratislavan government. Though possibly that's what all Bratislavan spies say). So...me, the Queen, Jenna Jameson. For everyone else in the world though there's the mighty Wik.
