I think that alone makes it a much better metric to judge the experience you'll have with a framework than its cyclomatic complexity (at least for a user of a framework, maybe not as a developer)
The reason it's impossible to find answers for how to fix problem X in Windows (besides it being terribly designed) is that there are a ton of users who are trying to be helpful and providing bad advice.
Googling for solutions to an Ubuntu problem is starting to look grim too. Read some bug reports on Launchpad and then read some on the Debian bug tracker; there's a clear difference in signal/noise.
Circling back to the original point: if a web framework is simple, you can figure out the problem by just reading the code rather than looking online for solutions (many of which are in the form "oh, framework Y automatically does Z for you so you have to...").
EDIT: Reading his post again, maybe he didn't mean that, but the point is still valid.
