You've probably already seen this video (like 4 million other YouTube users), which is very nice from multiple points of views. It is funny but respectful, uses many common sites (Facebook, Twitter, YouTube, Wikipedia, Amazon, Google Maps, GMail...), and shows how times are changing... probably from 20 years ago, not 2,000!
The two best ideas for me are the "avoid romans" options in the maps and the Magi who "follow" the star on twitter! I also wanted to take this opportunity to wish every blog reader a Marry Christmas and Happy 2011... even if I'll blog again in 2010!
BTW, the first person who sent me the link to the video was a catholic priest
