Ron raises a good point under my previous answer, so I decided to post another answer.
Maybe we should have a separate category, called "Community Wiki", and the same procedures that polarkernel did to zero meta reputation could be used on this subcategory too. We could use the category description to describe that this is for resources, and references, and other recommendations, on all of the topics allowed in Q&A.
Then, it will take less than an hour for us to recategorise the existing questions, and all new posts on these will go into this category too.
I initially thought of this a while back, but I didn't understand the argument for zeroing the reputation for CW, anyway.
Other uses of CW allowed by the StackExchange software, e.g. posting others' comments as an answer, can be done through the Comment2Answer plug-in, and even if another user decides to post others' comments as an answer, the author of the post can be changed by polarkernel's plugin Correct User.
