Blogging advice

I thought this advice on blogging from an Innovate Conference (Granger CC) breakout session was blogworthy. Good stuff if you have a blog or are thinking about blogging. Things I would strongly echo are:

• Be yourself - blogs where the author is always trying to "teach" you something don't hold my attention.
• Blog when you can and don't apologize when you can't.

I would add one:

• Be positive - I want to know what someone is for, not just what they are against.

And then the ultimate blogging resource: The Blogging Church by Brian Bailey
And then one I haven't read but understand to be THE book on blogging for businesses:
Naked Conversations by Robert Scoble
