Professional Debate or Fighting?

There is an article on SEO that is driving some interesting conversation. One of the threads of that article conversation is that the article is wrong / right.

That hasn't happened a lot on Biznik. There are relatively few artists or massage therapists who have come out and said "hey buddy, thats wrong", but in the SEO world you find a lot of personalities that are often fine with detailing the technicality of what is / isn't wrong. Firing a shot or two at another SEO is often the way business is done.

If I was an artist instead of an SEO expert, perhaps no one would argue with me (perhaps they would). Yet as an artist everyone listening to the conversation would equate my debate with intangible feelings and ideas.

In online promotion, many of the things I can talk about are intangible quantities - trends, forecasts, situational. A single period in my technical statement may make me algorithmically wrong.

I thought it was somewhat ironic that someone asked for "street cred" on SEO in the article conversation. I think that conversation is better suited for Sphinn, as 95% of the audience here wouldn't know the 73 different acronyms the SEO nuts are throwing around. (How many people even know what Sphinn is?)

If you can get 1000 SEO people to argue about what works... then I can only imagine the debate here would be entertaining to say the least. Without breaking into exact technical specifics of situational problems, then most of the debate is simply pointless! (Everyone is right... and everyone is wrong...) Just like art, there are a lot of colors.

As far as community goes- it right or wrong to tell another person that they are doing something wrong? Should it be done in public? Is it constructive or debilitating?

Does it matter if it is an artist, lawyer, real estate agent, or SEO?
