I still don't understand, don't we all agree that making the best product is not the only thing? Marketing, advertising, development, all of these are equally important. This was well summarized in this post (http://news.ycombinator.com/comments?id=23916 http://news.ycombinator.com/comments?id=23916 ). plentyoffish.com created something new and valuable. A free, simple, website, for online dating. It's not fancy, it's ugly, but it looks like it just works on tons of browsers. I agree, spam systems piss me off. However, I read plentyoffish.com's founder's posts on some SEO boards, and basically they give him good advice to make his product all around better. Ethical SEO sites basically say, if you have a good site, people will write articles about and increase your pagerank. So, it seems to me, SEO can be done ethically.
