1) Yes, I do use Internet to help me in my teaching, especially to help me with my lesson plans. I always give my email address to both my students and parents to get in touch with me when necessary, I mean, when I am available.
2) the major problem is the connection in the school and also that students tend to believe all the information they find on the net and sometimes this may lead to embarrassing situations in class.
3) it's obvious that times are changing and that technology will affect the teaching of languages, in fact, if we go back to ten years' time the way of dealing with languages is completely different. The role of the teacher is becoming to be a guide for the learner and my opinion is that this will be in the coming generations.
