I personally don't but I know a high-profile web-developper who does.
Now, how often do you guys actually perform upgrades on a production box (security aside)?
I go by this rule: If it ain't broke, don't fix it.
It should be noted that a lot of the important stuff is now off-loaded to language-specific package management. Python libraries are a good example with virtualenv and your-sensible-python-package-installer, the actual distro repository doesn't matter that much anymore.
