So? Reddit has about 10 sizeable Subs that are just a variation of "Ask Any and All Questions". That's not even counting speciality subs like "MedicalQuestions" or "ITQuestions" or "DermatologyQuestions" or "AskTrangender". Or the different language ones like "FragReddit" (German). In the end 1-3 will become the major ones, all will be a bit different and everyone will find the ones they like most.
