Darren Rowse over at ProBlogger has tested Performancing Metrics and calls it "VERY good" (emphasis his). In Darren's words, PM is "a statistics package that is specifically designed with blogs and bloggers in mind and that [...] can partially track AdSense performance."
Bottom line: Nick, you say this will be "something different, something better" than other blog metrics tools and services. Even if it's only ho-hum, it'll be better than most currently available blog stats packages. I'm really looking forward to trying it out. (Definitely would simplify my work as blog network editor ...)
