I discovered StackOverflow more than two years ago. SO is an amazing community for anyone who takes coding seriously. Whenever I have been stuck, SO has helped me; well, almost.
At the beginning all I did was asking questions. But recently I have started answering as well.
This is very good means of learning new coding techniques and strengthening the ones you have a loose grasp on. Simply browse the questions, pick one that you find interesting and set to answering it. The question should have a bit of challenge to benefit your skills/knowledge. Compare your method with that of other answers and you learn.
