A backlog of blogs to read led me to FeedMap. A cool idea of crossing feedreading with MapPoint. Just enter your address or latitude and longitude (straight from multimap or any other nice map site) and you get your very own BlogMap as shown below or local blogroll as on the right.
Also on the rise is Google's maps service. Crikey that's nice. I wonder how they got the maps compressed enough that you can drag and drop your map with almost nary a delay. V. nice.
