It's kind of curious to me about search because honestly my Internet world has only grown smaller and smaller. Where I used to use Google to find new websites, I feel like most of my searches on Google are now to search a handful of sites I already know. Ironically if Reddit had a better search function, a lot of my Google usage would fall off as I'd just go directly there, as it's still the best place I've found for troubleshooting support and real reviews of lots of products. A competitor to Google wouldn't really need to index the entire web for most people, but rather a relatively small number of website super giants like Amazon, Reddit, Wikipedia, etc.
