Fake meaning what? Doostang is just a ridiculous name regardless, but it might have served Google well to see if 'googe' had any other connotations (whether or not they're in Merriam/Webster) before putting it in a logo.
First, the stem of the cherry was intended to be the L, but it's acknowledged that it doesn't look that way.
Secondly, "Googe" doesn't connote anything, unflattering or otherwise.
When I say fake, I mean that people try to invent new words on urbandictionary, and not words that people have ever used before. Don't believe me? Then just click a letter on urbandictionary and read the entries sequentially instead of by popularity.
To sum up: the examples used in the article are completely ineffective, but know what words mean before attaching them to the identity of your company.
