It’s all well and good to have a revolution, but if nobody knows you’re having one then nothing really changes. There are still benefits to centralised services, one of which being scale. To effectively index so much data you need scale, which is why smaller search engines tend to be just white labels of things like Bing.

I feel like Google is going to have to find a way to effectively index federated content at some point. The only way to really get human information is from sites like Reddit and Twitter. And both of those platforms seem to be dedicated to completely imploding at the moment.
