I agree with his points about treating it like commercial software (in terms of having a website/screenshots/etc) but paradoxically the more professional an open source site looks, the more I assume there's going to be a catch. When you find a utility which has a site that looks like Richard Stallman's website you breathe easily because it's unlikely there's going to be any time-limited trial version, subscription models, ads-in-application, etc.
