I've written a blog article about Nimrod's features with the hope that it will attract some new users :)

Cool, nicely done and attractively laid out. It's the second Nimrod article to hit /r/programming in a month.
I got over 30,000 hits on my first article, so there's definitely a lot of interest out there.
At the moment we need adventurous hackers who are ready to hunt down bugs, not really ready for the mass yet!
