Wikipedia is "the mainstream consensus", a compilation of knowledge that is generally agreed upon by reasonably sane and well-informed people, in a format accessible by the layman. I think that will continue to be valuable. If you are a layman who wants to know "what is a computer" or "what is programming", then Wikipedia is a much better starting point than Stackoverflow or Don Knuths personal blog.
