I have difficulty remembering ten numbers, why do I have to say 1-212-487-1965 when I can just say Santa Rosita 71965? Maybe we should have just done another exchange name and added another name. Eg Hawthorne Santa Rosita 71965. I know its stupid, but 10 digit phone numbers are just so hard to remember and look at that I think its just human nature to gravitate towards the simplicity of telephone exchange prefixes.

Yet again, another fundamental misunderstanding (either genuine or not, I'm not sure) about the low-level technologies and their origins that underpin all of this. "Can't we just..."? No.
