Hello all, this is a very interesting post. I'd like to see if some ideas have come from it yet. Probably offline.

Not sure if I can post URLs, but the search engine/business directory I currently run is www.clickfind.com.au and one of the ideas was to involve SEO people and work closely with them, which is why we created the developers directory http://www.clickfind.com.au/developers-directory.cfm

I also have www.tiggy.com.au in the pipeline, which could be a work of cooperation with people from this list. Anyways, let me know where some of this discussion has led to so far, and see if I can be of any assistance.
