We currently have two questions that seem very similar to each other:
Between them they have 49 up-votes, 15 favorites, and 22 answers. Clearly these are important to the community.
Should they be merged? They cover the same territory and right now you have to go to both to get a complete picture. One of them is Community Wiki so merging it into the other would not have any reputation impact.
List/survey questions like this, while in-scope at the time these questions were asked, are discouraged on Stack Exchange now. Should we lock them (or the merged question, if we merge) for historical interest? The effect of this is to (a) add a notice saying "this is for historical interest; don't use it as a model of how to ask today" and (b) prevent changes to the post, including voting.
