While browsing around today, I found What are the pros/cons of a Canon SX30IS compared to Fuji HS 10 / HS 20?, a three year old question which to me looks like a question that is a bad question for all the reasons we now say: it's no longer useful as neither the SX30 nor the HS20 are still available, and it's attracted a number of the "XYZ is great" answers without any reasoning.
What's the best thing to do with this sort of question (I'm sure there's a number of them out there)? If it were raised today, we'd probably close it pretty sharpishly as "product or equipment recommendation". That's probably still a sensible thing to do with old questions, but is there anything else we should do?
