I do not think Quora is better than eHow. I have learned many valuable things on eHow, such as how to poach an egg. I have learned a lot of more complex and interesting things on reddit AMA's, such as how various businesses actually work. I have yet to learn anything on Quora. Every post I have read on Quora, aside from being long and pompous, qualified and generalized everything so thoroughly that it completely failed to impart any information.
