How do you interpret the 100 % figures at page 7 and things like the 17
% of "Vietnamese" users going to it.wiki per page 6? Such results IMHO
mostly show that Accept-Language is a very poor indicator of the
languages really understood by the user, as we've known for a long time.
The graph at p. 4 is more promising because it could tell us something
about the relative advantages of search vs. manual selection that the
users see depending on their conditions. We could discover more with
breakdowns other than en/non-en accept-language. The main take away
seems to be that for one population the search is 5 times more popular
than the links, while for the other they are very similar... but why??
