Robert Scoble vents off on some of what he calls non credible journalism.
Which prompts Nick Carr to post his 7 rules for corporate blogging.
Which in turn gets the people at Shadowbox Studios to publish a critique.

So is it good or bad?

I think ultimately it's about credibility, and credibility is accumulated by adding value to the community. It's no different from money: you sell  something valuable and people give you money for it; you can then spend this money in purchasing other stuff.

Credibility is just another currency, with its' own rules and exchange rates; it can be accumulated and leveraged and lost and re-gained.

Credibility can also be squandered, and there are examples of people wasting huge fortunes in a night.

I tell my clients: if you want to blog (or better, if you want to engage in any Web2.0 activity) you better be prepared to shift your focus from money to credibility, build your own credibility P&L and credibility Balance Sheet.

If you're not prepared to do this, better forget about the whole game.
