As of now, 4 of 10 newest promoted posts are about meetups, as well 4 of 10 newest posts overall. For casual readers like me, having frontpage flooded by this much irrelevant information, _especially promoted-section_, seems really, really discouraging. LW has tendency to contain too much useless meta-discussion compared to the actual rationality-related one, but having frontpage flooded by meta-discussion like this seems rather unbeliveable. Please, let's try to keep at least the promoted-section rationality-related.
I do find it annoying because I'll likely never be able to got to one for geographical reasons, but on the other hand I can see why it makes sense given how large a part of the readers DO live in the US.
The meetup posts are not limited to the US, fortunately. :)
