Rank Widget for Alexa, Technorati, Yahoo Search Inlinks and Google Page Rank

Go to this site to see how your blog stacks up.  This is a cool tool because you can check Google Page Rank, Alexa Page Rank, Technorati Blog rank and/or Yahoo! Search Inlinks!.  All in one place.  I'm not sure which one is the definitive one, but I think it may be Technorati.  What do you think?

I actually really like this tool, but wanted to note that you need to submit your blog to each of these blog rankers to show up and it's a bit of a process that will take a few days at least but well worth it!
