Which forums are you tracking/reporting on?
For this particular list we are using a rough estimate of unique users per month based on estimates from sites like compete.com and quantcast.com . These are often conservative compared to direct unique users per month that some MVP site owners have shared. It is meant to highlight how MVPs help a lot of user every month. This is also targeting only a subset of MVPs (namely, the US based Windows Desktop & Security MVPs).
We are continually looking at new sites & forums to recognize MVPs. If you know of a great location we should recognize (or a leader there that should be nominated for the MVP award) we’d love to hear it! We accept nominations for the MVP award throughout the year, and we award every quarter. You can nominate someone for the MVP award here: http://mvp.support.microsoft.com/gp/mvpnominate

Do you realize that the majority of System Center MVPs come from myITforum.com? There's some good security people there, too, plus with Forefront integration and System Center, and Microsoft Deployment Technologies, you might make note of it. Also, there's a lot of MVPs that particpate on email lists. That's tougher to capture, I guess.
What about Dell Community? http://en.community.dell.com/
It is a huge community that has several Security MVP's contributing.
That is quite a list, and I'm quite happy that I frequent many of those!d I'm also very happy to see Windows Desktop MVP's being talked about. We rock!
In that Scot's Newsletter is primarily a Linux support site, based on the distribution of threads and postings, I don't understand how it made this list.
