There are tons of blogs, forums and hobbyist sites filled with useful info, but they're drowned out in search results by SEO spam sites. It seems search engines could identify quality sites by asking users to click an "is this useful" link.
Or have any dedicated hobbyists created curated search engines in their realm of interest (cooking, gardening, automotive, software, etc.) that limit results to a range of high quality, non click bait sites?
