Problems with Google’s Technology
Jeff Dean, a Google engineer, also talks about Google's technology a bit in this video at:

Since Google has the broadest distribution, people also work the hardest to game their system.
Google tends to take the view that any relevancy manipulation is inherently wrong and the SEOs are the enemy. In doing this, Google often prevents many quality resources from ranking and ends up having substandard relevancy. It seems they would rather make their own results slightly substandard than allow others to manipulate their index.
Currently, Google's algorithms place way too much emphasis on domain age and trust. This will lead to a stale index, and worse yet, many spammers have been buying old sites (or finding content management issues trusted sites) and adding tons of spammy content to them. A relevant thread worth reading about how easy it is to game Google with old domains can be found at http://www.threadwatch.org/node/6484.
You can also use SEO for Firefox or Archive.org to see how old the average, top-ranked site is for your primary keywords. Typically the top-ranked Google results will be older than the top-ranked results on other search engines.

Google are continually moving the goalposts in my opinion. It's a search engine and should do it's job by returning the most relevant information for the search. That should be it. If someone wanted to by cigars from a site that is 7 years old wouldn't they type that in to the search box? To me it should always be the most relevant not the oldest or google's best buddy.
