Karl Ribas posted an interesting article about the wrongfulness of gaming the Sphinn system. He feels that good content will get there by itself. Below is my own opinion.
The goal of sphinn is to get relevant information to the right people. As people that are involved in SMO, we all know that the more we have connections / relationships / links / authority from other people in our industry, the more we can do.
While I can't sell my search marketing services to a search marketer, I can refer an SEM client, if I only do SEO. Or he can license my software, I can learn his technique regarding Log analysis, subscribe to his feed, get a reference and so much more.
The best way to gain credibility is to get a referral from someone else. I see nothing wrong with "gaming the system", as long as the product / information you are providing actually provides value to the end user.
(If my goal was to gain more friends to game the system, I just messed myself over!)
I do believe that Karl probably wouldn't argue with most of this. It's more a matter of a bunch of idiots that don't know how to provide valuable articles to sphinn, and would rather spam a tech savvy audience (idiots).
