I see the idea Dan, but I also see the result of what it would do fairly clearly.
I can see the relevance of working together as a community, but I have a technical issue with the idea of categories that directly promote other community members in my field- rather than promoting the community itself as an entity.
If the model changes, rather than be a community of indies I am a competitor in a category with other SEO/online marketers. This sort of effect occurs slightly here in the biztalk chat area, where some people insert random commentary to stay on top of certain results. Right now we are not competitive for business, merely socially / community competitive in sometimes a fun way (I've laughed a few times with people who have been bumped from here to there)
The shift of community member to competitor happens because of the prospects origination from the search engine. They are most likely to do business with the top person, which will drive results for some top members, and the underlying members will struggle to get on top of that monetization. All of a sudden we are not using location to be members of a community, but using our location as a method of lead generation.
Right now- I (and many other members) of Biznik are supportive of other people in similar fields, mostly because we are not in direct competition for the same prospect (community vs lead gen). If I suddenly have to be on top of something (like an SEO category) for lead generation, I have no other option but to be competitive... there is only one top spot.
I'm bringing this up frankly because I'm one of the most supportive-collaborative mindsets I know. If I'm seeing a competitive conflict, then I can only assume that 90% of the community would stumble onto it too.
The only real answer to keeping a natural competitiveness from kicking in would be to not rank the category pages.
The conclusion: If you create a high importance spot on Biznik, you are creating a high importance spot on Biznik. Unless everyone can have one, it isn't fair of me to say "yeah, sounds great" knowing I'm probably going to be on-top of a category and reap the reward.
Item#2
I am not saying the algorithm here doesn't needs work, I have no idea why a quickbooks consultant or professional organizer shows up for SEO.
I love the business networking community of Biznik, but the category idea isn't a networking community item, it is a lead generation item. Category landing pages and onsite member search tools are two entirely different things.
I would probably think it is easier to fix the second item by limiting the searching to information on my profile.
