Yes, really, because PerlMonks is a community, not a technical manual, and it does have the best signal-to-noise ratio I've seen in any community. If they want the signal-to-noise ratio of perldoc.com, what are they doing in a community?
Your original statement said the best signal to noise ratio of anything. Not of any community. Anything.
When you add that qualification, I still think you are wrong because I have seen communities with better signal to noise ratios than PM. But not communities of general interest to Perl folks.
