I know that English and US American usage differs here. I always use "like +ing" when I mean that something causes me pleasure. I like eating in restaurants. (makes me happy) But I use "like+to" to talk about something I do which is convenient or generally a sensible idea. But don't necessarily like. I like to go to the dentist twice a year. I dislike going to the dentist but wish to conserve my teeth. I like to do the housework in the morning. I get it out of the way and can do other things after lunch. I like to get up at five in the morning and go for a ten mile run. I dislike getting up early and hate running, but I'm a diabetic and it does wonders for my blood sugar. I teach English for a living and have seen that many modern textbooks now claim that these two forms are both correct and interchangable. If this is really so, haven't we done away with what I consider to be an important shade of meaning?
