infographic: How Does Google Work?
I’m a little behind the curve on this one, but a co-worker sent it to me yesterday and it’s pretty interesting. It’s a very detailed graphic/flowchart on how our pages, blogs, tweets, etc. get processed through the juggernaut that is Google and wind up as search results.
It’s impressive and more than a bit awe-inspiring, but that won’t stop me from sending people to Let Me Google That For You.
