Lots of business and org names are acronyms, but it really stands out to me how most of the early ones are short. I guess in the age of excessively-long UUCP addresses, it was immediately obvious that short domain names would be preferable to longer ones.
It's a deeper reason than that. Humans are hardwired to start with short symbols.
Picture a group of humans who evolve a new language. That language will likely start with short sounds, and then progressively build up to longer sounds.
