My tip as a user who just stumbled upon this link on HN: Have a good easy-to-find 'about' link on your Blog. It took me a good couple of seconds before I was able to find a way to get to the root website and read about what you were about. It would be nicer if there was a quick 'What is ProjectSherpa?' link somewhere, or maybe a quick 2-sentence blip on the sidebar explaining what Sherpa does. I'm sure other readers would have given up sooner and bounced from your page.
in any case, good luck to ya!
