The "freshness" issue is one that causes problems and subtly sets priorities.

Problems come up when looking for older content on purpose. A lot of older content is very relevant still today. I know people who could not find something they knew existed in Google. Switched to Bing and it came right to the top. The difference was the way newer content was prioritized.

Google doing this sets priorities. It says that newer is more important. Is that true? Many would argue it's not. Google says it is and "advises" people where to go based on that.

I find these worth considering.
