Even though I had my personal interest to learn English, back when internet was not common, or not very accessible due to dialup, i would buy English newspapers and study them, and always keep a dictionary with them. However, that was bit silly and a lot more time consuming. The best to improve English is to be part of a community (an online forum). it's up to you which you want to join. Only join the one which interests you. Get involved in lengthy debates and discussiona, I know it's not cool, but just for the sake of learning and improving your English. If you follow up above advice, your English skills will skyrocket in a very short time compared to traditional methods.
