In my opinion very few metrics have any bearing on much on many forums.

Speaking generally for various edged tool forums, I have read utter garbage posted by people that had 10+ years of tenure and over 10,000 posts on the forum. I have had people tell me "STFU noob" because they were older and or had a longer standing membership, or had a higher post count.

Here is a fact you can take to the bank: stupidity does not shy from high post count, long residence time, or old age, idiots can exist anywhere.

I am happy to report that this site has a lot of good info shared freely and not too much muscle flexing based on these metrics.
