However even that modified example, still doesn't really reflect on the problem the average user will insist what a great trick it was to use reddit to try and focus results. The average user unknowingly ignore a lot of other areas on the web that they could be using to focus what they're looking for. I guess that's one of the things A.I. will be able to do, something similar to what the old google search algorithm used to work where it seemed like google could work out of the number of search terms which word was a focus word (often a broad term to cover the field the rest might be common in.)
Like I stated in the last reply, a site going dark, it's not a google problem. Google's search has sucked for a few years ... and I know for all the hard to find or failed things I couldn't find since whenever, including reddit would have had zero effect.
If the grocery store is relying on one supply chain for a large percent of their products, and they lose access to that supply chain, it is the grocers' issue. Saying "well technically it is a supply issue and could happen to any business" is missing the point when shoppers are displeased with what is available. Saying it is really reddit's fault is missing the point that Google SEOed itself into a position where they did not have a robust supply chain to relevant results people were searching for and now their results shelves are empty.
