I find it hard to believe that Wikipedia is "in decline" when the article I wrote about the niche area of CS I worked in during undergrad has a life of its own now. People continue to add to it and now it has a fair deal of content and information that I was unaware of. If that's what decline looks like, I'm fine with it.
