Google turns eight today. I think I'm supposed to maintain some sort of journalistic remove from congratulating it directly, or drooling my praises for its good work, or generally being in awe. So I won't say that stuff.
You can try to see how the Google home page has morphed over time at the Internet Archive, but most of the logo images are broken. There's a fun discussion about Google's birthday at Google Blogoscoped, and Barry at SEW says there's some confusion over the exact birthday date.
