I was trying to remember how I felt early on. Google didn't seem silly to me cause it just made me think of the number. I do remember 'Amazon' sounding like the batshitcraziest name you could possibly pick for an bookstore though.

Silly names become brands, wherein the name becomes irrelevant IMHO. I've always thought so thinking about 'Tool' as a band, and how the word itself, is silly. But you wouldn't notice it (symbolism etc. aside)
