It's true that people find things by googling them, and so it usually doesn't really matter if a hostname is www.gimp.org or eqt5g4fuenphqinx.onion, while it does really matter that the search link via www.gimp.org can break suddenly for no good reason. It also matters that the pages at eqt5g4fuenphqinx.onion are dependent on a server operator.
