Blogmap
Roll it out, the blogmap. I found this feature which will show you bloggers who are around you.
You will need to set up several things first though. With my minimal blogging know-how, I managed it, so I think most people should be able to manage too. :)
You'll need to put these lines in your blog's meta data. The <head> tag should come first and </head> tag last.
<head>
<meta name="ICBM" content="(insert your latitude), (insert your longitude)">
<meta name="DC.title" content="(Insert your blog name)">
<meta name="geo.position" content="(insert your latitude);(insert your longitude">
</head>
Note: Where I've put, for example (insert your latitude), it means you do that. Do not include the parentheses in your syntax.
The first line is for facilities like GEO URL to recognise your blog position, your server position doesn't matter and to most people is of less interest than your physical position, i.e. where you are blogging from.
The second line is quite self explanatory.
The third line is for facilities like Blogmap (you could find the link above, and see the icon after the picture of my spring bud) to recognise your position.
Naturally, if you don't wish to use GEO URL, which recognises both html and RSS, you could drop the first line. Blogmap, as far as I know (I might be wrong), only recognises RSS.
If you wonder what those abbreviations mean, I'm not about to tell you, simply because I shall make a very poor teacher. It's best if you Google them.
