My definition would be this...

1) Google - has Feed Reader, deliver new content to users via its new and updated feeds, has adwords on the feeds, generates money....

2) Google - indexed fresh updated content with what is happening in todays world. We go to Google, do a search and get pages thrown up that are several years old -
Move over Google hello Yahoo and Live for more searches!

Not to mention - both yahoo and Live are lagging behind behind Google because they weren't quick enough to catch on to the next generation of money spinning opportunities being presented to them.
