Great comments thanks for posting this. You bring up some good points on the graphs. This was mostly quick and dirty stuff I hacked together and could certainly be improved. The 'noise' doesn't seem to bother me though and helps me compare them visually, could be a personal preference thing. On the SEO use of subdomains, do you have any links I could read more on that? Anecdotally, my experience seems to be otherwise but I could be wrong. Agreed that the blog needs better maintaining. I'm more focused on my personal blog to do much with it. I've tried getting some tutors to contribute with mixed results. I haven't had much luck with the quality of articles when hiring someone to write, so not sure of the ROI on that. If anyone has ideas would love to hear it. On that A/B test, funny you mention that because I tried almost that exact thing you suggested when 37Signals came out with Haystack.com (now Sortfolio.com), where I made the free tutor account permanent and the paid account got you top placement in search results, highlighted listing, and a 'PRO' badge next to your name. I didn't run it long enough to have 100% confidence but the conversion rate dropped compared to what I have now (first 3 job requests are free, then you must upgrade if you want to continue). I still feel like the biz model could be improved though. If you have other ideas on this would love to hear it. Thanks again! Brian
