That depends how you define it. My cat has a skin blemish on its paw. Does documenting this fact add to the sum total of human knowledge? Technically yes, but

That depends how you define it. My cat has a skin blemish on its paw. Does documenting this fact add to the sum total of human knowledge? Technically yes, but it's of no interest to anyone. But there's an even continuum between this and academic papers of great import - what if I figure out the best strategy to defend against a Zerg rush and post it on a forum? What if I figure out a really cool new programming technique and blog about it? What if I write an academic paper on obscure characteristics of hyper-complex non-euclidian non-reimannian Q-manifolds in P-time that has no ramifications for anything and is quickly forgotten? But then what if a tremendously important application is discovered 50 years later? Especially with the internet, what qualifies as human knowledge becomes completely blurred. Previously the qualification was probably getting published, but now anyone can make information available to anyone else and the rest of posterity.
