they can't be ranking everything on how fresh it is because it wouldn't work.
i want my newspapers fresh every five minutes, but i don't want a music shop that only sells the charts. and no one's going to like a bookshop that doesn't stock the classics.
the vast majority of information sites must be immune from this freshness stuff, surely.
imagine if you search for a poem, or a quote from a book. what does it matter how fresh it is?
I agree londrum, for evergreen trophy KW maybe the rankings won't change. But for long tail KWs it may become based on freshness. Here is a simple example.
Say the trophy KW is Widgets.
Google's may treat the ranking for Widgets one way but not for say Green Shiny Widgets. Why?
Well content about Best Green Shiny Widgets For 2010 might be looked upon as fresh thus favorable, and could very well out rank older content targeting the same KW.
