Yvain isn’t talking about rationality, he’s talking about membership in a rationalist group.
My understanding is that one’s rationality (or ability to be rational) would increase as a result of participation in rationalist training. Hence, I see your disctinction, but little, if any, difference.
In this case, he assumes (1) LW is rationalist and (2) LW is good at providing training that makes a participating member more rational.
Karma does not necessarily have anything to do with rationality, being rational, rationalist training, etc. It is a point system in which members of LW give points to stuff they want more of. It has also been used as a reward for doing tasks for free for LW, mass blocks of downvoting for dissenting political views, and even filling out the survey we are talking about in this post.

...(3) No one turns up as a newbie at LW having already learnt rationality.
That it, is in fact, the question Yvain is discussing.
