Library Code People:

1 - What do you use for your web statistics package?  Are you happy  
with it? Pros/Cons?

2 - What do you wish you used or had access to?

3 - Opinions on Specific Projects:

3.1 Piwiki/Mint

Piwik and Mint both seem pretty interesting to me because they solve  
some of the problems of "traditional" log file analysis (see http://www.boxesandarrows.com/view/the-limitations-of#comments) 
, while of course introducing their own set of problems:  given their  
reliance on a RDBMS to store each page load, there are some obvious  
scaling concerns for very high traffic sites, for example.

I wonder if anyone here has put either of these or similar systems to  
the test on high traffic (define in your own terms) sites.

3.2 Google Analytics and/or Urchin

Some libraries have incorporated Google Analytics into their privacy  
policies: http://www.google.com/search?q=google+analytics+libraries+privacy&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a 
  .

So, anyone here passionate one way or the other?  Other Pros/Cons?

Of course, favorite resources, questions I should be asking and the  
like are welcomed and appreciated as well :).

In advance:  thanks!

Cheers,
-Chad
