During last year's Thanksgiving dinner a friend asked me about how to go about creating or finding a Craigslist tool to better support buyers and especially buyer intermediaries. The first step has nothing to do with technology. The first step is to clearly understand what the tool should do and how you would use it. The outcome of our discussion was the Craigslist Purchase Hunter requirements document. It is suitable for use as an RFP. If you decided to build this tool please tell us about it. Good luck.
