Really, I hate to say this, but SEO still has way too many dodgy players for many people I know to want to "join" it. If there are any Good SEO types (not sure how to define that) out there, can they please write some blog posts about why they should be trusted? Accept the fact that the industry has been blemished by snake-oil salesmen and try to fix it with truth, rather than PR.
I know, I sound angry, but I've seen companies waste tens of thousands of dollars on SEO and haven't seen much evidence of the other side of the coin. Please, convince me this is a valuable part of the web ecosystem!
