This is a legitimately evolving question. While the community wiki and voting systems partially deal with the problem, there remains the difficulty that at least some of the old answers to questions such as this one are going to lose relevance over time. Is there any policy/user moderation strategy for dealing with this type of situation?
In the case of the above question, the poster was immediately linked to three iterations of essentially the same question, which helps establish the lineage of answers, but at the same time it's going to become frustrating to ask that question over time as legitimately new languages and development frameworks emerge. I have to imagine that there are other questions which behave similarly.
