I voted "How To". Especially if they are loaded with key search engine words. If someone is trying to find an answer about non-reving and this site pops up first & multiple time the searcher will say "That place must have all the info I need". I think the topics you suggested in the "Paid" post are great starts, epically the ZED one. I've heard more co-workers asking about ZED issues than any other travel question.
