Blogwise lists over 50,000 blogs in its directories for you to browse. Those blogs that have position metatags in their headers can now be browsed in Google Earth via a dynamically generated KML file that lists the 50 blogs closest to the center of your view.

If you don’t yet have Google Earth (i.e. you are a Mac user) then you can still do this via Blogwise’s Blog Maps. The advantage in using Google Earth, however, is that you can see more than one layer of data at a time. In Google Earth, you can now simultaneously see the closest Blogwise blogs, del.icio.us links and Flickr photos if you want (and a lot more). We’re beginning to have some serious functionality here.

So, if your blog hasn’t been submitted yet to Blogwise, perhaps now is a good time. And if your blog does not yet have positioning metadata, here is what you do: Use this souped up version of Google Maps (in Satellite mode outside the USA) to center yourself on the map, find your latitude and longitude (displayed below the map) and then use these instructions to add a position meta tag to the header of your blog.
