May someone update manual in which it is written that Wikipedia is the fifth site by traffic? For the most of 2010 and whole 2011 it has varied between 6th and 8th place [1].
comScore, Alexa, &c use different methods. comScore is not perfect, and has known biases in its coverage, but it is a bit better than Alexa in that regard. (We used to rely on Alexa data and moved away from it)
I would love better data - if you have a better source, or a better way to describe the data from multiple sources, that would be a great reason to update our public docs. But just replacing comScore cites with Alexa cites won't be an improvement.

As far as I understand this, that would mean that saying "Wikipedia is the fifth most visited website" is still completely wrong, as the comScore data is an aggregate of the various Wikimedia wikis.
Those are all aggregates of multiple projects. Most of the others use a single TLD but they aren't single 'sites'. [for SEO purposes, we would probably do better if every project shared the same TLD the way Google's do, but that's another thread.]
