It wasn't supposed to be a scientific study. It was just an indication that whilst some people are very loudly objecting to Win8, that doesn't mean that everyone hates it.

Wrong.  Those search results are 100% meaningless, due to the fact that Google sucks.  Any page which contains the words "Windows 8" and "great" will show up in the search results, even if the word "great" is used for something completely unrelated to Windows 8.  And, if you dig into the search results a little (basically anything beyond the first couple of pages of results) you'll find that most  pages contain "great" but no mention at all of Windows 8 at all.  That's why there are 24 Million results for "Windows 8 killer pigeon".
