I received the banner ad for Careers 2.0 in French.
What made it decide to do that?
Was it because I asked Learning a bit of French with not much time on the French Language and Usage site?
Was it because I spend a bit of time at the other language sites, including Japanese Language & Usage, and English Language Learners?
Was it random?
Does Stack Exchange follow my twitter feed and notice me responding to someone's pleas for help with French?
