The size of Canonical's support organisation has nothing to do with its ability to support its
customers - it's reasonable for the support staffing to scale to the customer base. A
UK-based Linux magazine rated Canonical's and RedHat's support as tied for first place in an
August 2007 publication. While the plural of anecdote isn't data, it was certainly a nice
award to achieve.
(obDisclosure: I used to work as the Operations Manager for the Global Support and Services
department of Canonical, and started the commerical support department. Forgive me if I feel
the need to defend it a bit. *g*)
