If you're really into maps and stuff, get out GeoBloggers.org. It's a shame, its kinda changed directions lately, but you can find links there to good sites. A lot of people in that community work on things such as incorporating GoogleMaps and Google Earth with their Flickr photo sites which make an awesome mashup.
I've been meaning to start a thread about this, its called "Geotagging" and from what i've seen, its pretty tight. If you look at it, let me know what you think.
and welcome to the boards!
