Gmail's Christmas Card:
Some people noticed a new Gmail login page specially created for Christmas (or holidays, if we want to be politically-correct)."There may be snow outside, but hopefully there snow spam in your inbox. May your inbox be filled with joy this holiday season and beyond."
Gmail didn't add an option to create Christmas cards, but YouTube lets you send video cards. You can also add the Holiday Village theme to the iGoogle page, download some Christmas gadgets for Google Desktop, try to guess what's the next Google doodle and track Santa in Google Earth.
