But what i can say is this information is already used by google. I have experienced this back in 2008.
Take for example the recent firefox error that was discussed in one of the threads earlier.Being relatively a new version, there wasn't much info on that error in the first few days. There was just one or two sites which provided the answer.But in one week's time the web had several pages offering solutions for that error.Yet, the original two pages continued to rank higher.
There can only be two reasons for that.
1) Page history 2) usage stats.
