Acronyms Perfected! Relations Organic/Obvious! Now Your Memory Scintillates!
The expansions may describe people known to the apronymists, or something about the origins of the names. Many people search the site for first names, perhaps expecting an expansion describing themselves. Without knowing anything about the person we can't create a relevant expansion, and if we did the expansion would not mean much for somebody who did not know that person. Many of the first names we have expanded probably suffer from that lack of relevance, but as they are so often searched for we feel as though some kind of expansion for a name is better than nothing... perhaps, like horoscopes, they can be interpreted to suit anyone to some degree.
