What do you think of forums in terms of learning?
I think that it is a great place as you can discuss any doubt with global community and you can resolve your doubts as well.
But one thing I'm not sure about that all the replies and answers may be true you also have to use your common sense as there may be any kind of members newbies as well as experience.
It also depends on the forums, on some forums moderators would also help you in resolving your questions..
