dont you thing this section is redundent?

I don't think Q&A is redundant as there are new members coming in every time and even if some of the questions are redundant, the people who respond are different. Q&A has more activity and also gets frequent questions and general discussions are more relevant to a huge spectrum of people than the more specific ones. Q&A fits in almost any type of topic and I love variety, so I prefer Q&A to other interests. It is also more approachable than some other interests. Have a nice day!
