Ever since Eco SE got in beta, I don't see much point in keeping Quant SE around other than having another place to ask math questions when you reach your limit on Math SE if Eco SE graduates from beta.
Some finance questions are too basic for Quant SE but no finance question is too advanced for Eco SE, so it seems. It seems like any question on-topic here is on-topic somewhere else in SE. Suppose Eco SE graduates from beta, is there still any purpose for Quant SE?
Also, please give me an example of a question on-topic here that is not off-topic elsewhere in stackexchange or stack overflow.
