Same as many, I learned English mostly by reading the web and watching TV show in English (with French subtitles, as I my mother tongue is French). So I firmly reject the notion that learning a language has to be done trough rote memorization. Curiosity about words/idiomatic expressions you don't know is important tough. But stopping on each single word you don't understand is certainly not the way to go (well except if you have to, as in schoolwork).
