Have to say this is one of the best plugins that everyone should use. Its easy and simple to set up and helps drive traffic to your website or blog and you can help drive traffic to other websites and blogs.
Nice plugin overall.. looks good and doesn't seem to bog down speed like a lot of other "related story" plugins.
I'd give it 5 stars if it could exclude categories. I was surprised to see it didn't.. seems like a no-brainer and would not be too hard to code for it. Maybe someday...
