well, if only categorisation of extremism online were better. Recently I was searching youtube with the word "Lokiarchaeota", an exciting very recent find in the origin of the eukaryotes, hoping for a scientific lecture, and was mostly getting creationist preachers as results.
Who the hell searches for priests by naming obscure microbes ?? And sadly this is hardly unique; i've been bombarded by UFOs, reptillian aliens and similar outlandish nonsense in search of factual science regularly. And its clearly not doing a reasonable job at predicting my interests at all, for those are not items I'd view.
Why google's imbecilic algorithms promote and push such extremist trash on the general populace is beyond me, degenerating many neutral search results page to worse than reading the yellow press, but this does sadly seem to be what's currently happening, and would reasonably lead many away from wonders that Internet could offer instead.
