And yes, I do think for any company out there crawling the web, RSS feeds are a good indicator. Ofcourse, Google algorithms got to the point that they don't really need RSS feeds anymore, but that's perhaps also the reason why quite often their search results kind of suck, as soon as you dive deeper.
The real problem, for all of us out here - is that no-one even bothers making a search engine anymore.
Everyone has given up. And Google can just do whatever they want. And that's exactly what they do.
