Quantlib userbase

Hackson, David
Hello.
I have a quick question about the QuantLib userbase.
QuantLib looks like a very exciting project!  I am trying to descern the current userbase (and growth).
 
The sourceforge download page lists the number of quatlib downloads as ~400.
http://sourceforge.net/project/showfiles.php?group_id=12740
 
But the sourceforge statistics page says there are 150 downloads per day (or 11,000 in the past 2 months!). http://sourceforge.net/project/stats/detail.php?group_id=12740&ugn=quantlib&type=prdownload
 
What is an accurate estimate of the userbase?
 
Thank you very much,
--dave hackson

More like 2000 (you should look at the QuantLib 0.8.1 packages and add
up .tar.gz and .zip archives.)

I wouldn't trust this one a bit.

An accurate estimate is difficult to obtain, even assuming that the
2000-downloads figure is accurate. Were I to mention a figure, I'd
choose the number of subscribers to the mailing list: according to
<http://sourceforge.net/mail/?group_id=12740>, that would be around 900
for the users' list and 350 for the developers' list.

Later,
