I'm looking for a post in AskMetafilter that happened within the last year or so, I'm pretty sure. The poster had moved recently to somewhere in Canada or the northern U.S. from elsewhere in North America and was dismayed to find that people there seemed to only talk about themselves and never ask questions of others. The post got lots of replies and the consensus seemed to be that it was a cultural difference within certain areas in North America regarding whether it was considered polite to ask questions when meeting someone new. Anybody remember this one? I've tried searching for all the terms I could think of.
