As readers here know, I love Flickr. From the folks that brought you the great photo site, now we have Mappr. Mappr taked the meta tags you create on your flickr photos and maps them to places. I need to explore it some more but it looks pretty cool. I have frequently taken pictures of places I go as sort of a visual documentation of what I see as I walk around. This adds a really cool new dimension. Assuming you do the whole tagging thing. This is where you get a good visual overview of it.
