All the results for "e os" are about /e/OS, and that's its full name, so you wouldn't just search for "e". D language is a better example — its just called "D", but searching for that doesn't give results about the language. On the other hand, for "C" and "R" the top results are all about the languages. "Go" is also a pretty bad one, they insist it's not called "golang" but you basically have to search for that to get any useful information.
Yeah but when e/os first changed their name it was much harder. I have a feeling these results have had some human help.
It used to be called eelo but some prick thought it sounded too similar to his one man consulting company and threatened to sue. In the beginning it worked much better to search for the old name.
Why don't these people/companies think about how hard it will be to search for their $thing !?
