No! Forums are very much alive in lots of places on the web, and still provide an excellent vehicle for all sorts of communities to converse, joke, console and advise each other quickly, easily and in a logical format.
you only have to explore some of the forums to know that they are still alive and kicking! for example check out forums catering to expats in various countries or technology forum be it forums related to mobile devices or broadband services...all of them are so alive with content and conversations! I rely on these forums to provide information that i consider is more relevant and useful and allows me to evaluate options and choices based on real user experience.
