I recently ran across MyBlogLog (at InstaBloke) where it was tagging outgoing links and ranking them in terms of popularity. I thought to myself "That's kinda useful" so I've whacked it on this site (without link tagging for the moment) to see how well it tracks things. Since I normally use SiteMeter I'm interested to see what the difference will be.
While I'm going on about "useful" things. I also found a nice web page that does trackbacks since blogger doesn't support it. Thanks to Ohad for the link.
