The trouble point I'm annoyed at with anonymous is that if they are using an authorized source, we have to check the same source, it's a waste of time for me to re-check what they (supposedly) already checked: "This note includes comments from anonymous users which should be independently verified." --sigh.

Also note for other mappers who contribute to editing the USA and not familar: TIGERweb on census.gov is even more up to date than what we have built-in to iD so they may be checking there.  Again duplication of work that really shouldn't need to be done if they would just create an account...
