Over the last year Twitter (and Twitter applications such as Spy and Friend Feed) has become my favourite research tool for finding new Google Maps mashups.

Last week I was in the process of putting together a list of Google Maps related Twitter users to post on Google Maps Mania when Twitter released their new Lists feature. Here is a list of lists (a metalist?), that have been compiled by Twitter users, that are geo related.
