David Newberger has put up in his blog a 10-question interview with Doc Searls. Doc is at his usual best. Liked the last Q&A in particular
What advice would you give someone who is just starting out blogging?
Think of every post as an email that's cc:world. Don't worry about making mistakes. Be yourself. Write about what interests you. Link a lot and follow other links. Follow subjects through keyword search subscriptions in your aggregator. Drive ideas. Participate. Write with provisionally, rather than finality (leave that up to the big-time print journalists who are paid to pontificate). Start snowballs rolling, and add snow to ones rolling by. Be humble. Make mistakes, correct them and move on.
Oh, and use your own name. Don't bury your identity.
