I can sort of see the benefit of using it as a serialization format. Use it to replace the db for some things or instead of a configuration file. It might be nicer to send it to a data store then have to write into a file...

However, doesn't this turn it into the mother-of-all global variables? (Actually, if it's outside of the globe, and outside of the system, can we call them galactic variables?) With in-memory lists, the scoping is relatively well defined. It seems like the temptation to take this too far would be great.
