The survey shows that three systems lead the race: WordPress, Joomla! and Drupal. The survey concludes that these three systems have opened up a large lead on the rest of the pack to become the dominant brands in the market.
The author, Ric Shreves, states: "WordPress enjoys great brand strength courtesy of two complimentary offerings: the WordPress CMS and the WordPress hosted blogging service. Nonetheless Joomla! is positioned to challenge for the lead in brand awareness." He added, "Though it might be surprising to some, Drupal is not far behind. The survey showed that in the crucial U.S. market, Drupal is essentially tied with Joomla!"

Those are some amazing charts
This is going to be crucial information for a lot of people that need to make justifications for IA decisions to managers / administrators about strategic direction. Though I am somewhat surprised at just how popular WordPress is as a whole.

Fascinating stuff
Wow. Though some of the methodology is limited, there seem to be soooo many lessons there for Drupal to take. So many ways we can be improving our visibility and image (though I've noticed that we have started to take quite a few steps). It's disappointing to see that we were not able to provide them with download numbers. However this survey is like gold for knowing a few sweet spots to hit over the next while. I was surprised how consistently we ranked third and there is plenty to do to catch up, particularly to Joomla, who seem to have been doing a much better job on the marketing end up until now. Regular press releases, more tooting our own horn, more talk in the ether, better tracking of Drupal installs (maybe some kind of optional notify built in to core?), etc. And questions, like does their blog search include groups.drupal.org and similar?
Of course I'm likely misinterpreting some of the data, but it does seem like there is a bit of a trend towards Drupal, but also that there is much to be done. Glad this is your job and not mine, though I would love to see your analysis of this data.

As of Drupal 6 the core
As of Drupal 6 the core update status module not only allows for tracking Drupal installs but also which contrib modules are being used. It can be turned off, but I guess enough people will see the benefits of using this module, since it helps to keep their sites up to date.

My comments to the authors
1) http://buytaert.net/drupal-download-statistics-2008
- Bear in mind Drupal is a heavy development community and many people manage Drupal via CVS and Drupal shops lean towards the large size and often run their own internal code repositories. That results in less downloads.
2) July 10th was a security release, not a major feature release so there isn't usually a lot of press about security releases.
3) I think your choice of job sites greatly influenced the results. If you had picked sources like craiglist, linkedin, simplyhired you would have seen much more even results. eLance is biased towards outsourcing. Drupal will also have less public postings because it has over 1000 job postings at http://groups.drupal.org/jobs?page=22
4) Joomla.org's search engine is Google. Therefore all their site search traffic skews their Google trends status.
I think one of the things you could add for your next report is industry adoption. Drupal does very well in Education, Non-profits, Media, Newspapers. I also think a qualitative assessment of showcase customers using a product can have a big impact. Lots of large businesses(NPOs, Education, Media, Newspapers) are moving to Drupal.

Truly amazing stuff. This
Truly amazing stuff. This kind of data can be used to our advantage. Based on my research I don't think that either Joomla or Wordpress are anywhere near as customizable, but I am biased now. Great comments too, Amazon.

The announcement about
The announcement about Drupal being on the top security reporting list echoes these findings. All three are on the list, and I think this illustrates the importance they have as a crucial part of web infrastructure.

It's worth noting that these
It's worth noting that these statistics are for reports rather than vulnerabilities. Drupal reports every vulnerability found in core or contrib, even very minor ones - whereas many other companies/projects don't take on responsibility for contrib (i.e. Microsoft doesn't include firefox vulnerabilities in its stats, it's unlikely that Wordpress handles security for all external plugins and themes either) - and hence their reports are for a relatively smaller percentage of applicable code base.
Needs Repeating...
It really is astounding how few people understand the very basic points about security you've made (which are true, when abstracted, to any sort of security studies).
Does ignorance of insecurity make one secure? Microsoft would certainly have you believe so... :P

OT: disclosures vs vulnerabilities.
Clearly, there is no 1:1 relationship between the number of reports and the number of current vulnerabilities in a project. Even if we would not have reported vulnerabilities, they would still exist.
However, as we 1) distribute contributed modules, 2) depend on contributed modules for most functionality we need to 3) take ownership of the problem and fix the issues.
Whether a burglar gets in through the door (core) or a window (contrib) doesn't matter much for the site owners with a hacked server.
Good to read
A really strong read. Thank you for posting.

I think one of the reasons
I think one of the reasons Joomla's backlinks are so high is due to the fact that most Joomla sites include a link to joomla.org in the footer. Drupal only introduced this in version 6, but hopefully it will help us catch up to Joomla's level of exposure.
Another thing I noticed is that awards with "Linux" in the title seemed heavily biased towards Mambo and Joomla, but Drupal still had more awards if I recall correctly.
