If you read blogs, then you've probably read Seth's blog. Seth is a prolific blogger, posting regualrly with short, thoughtful, sometimes acerbic posts to challenge the way you market your business. And pointing out what others are doing well and not so well.

He's also written lots of books - the most famous  being the ebook Unleashing the Ideavirus - and is in demand as a conference speaker.

Unlike most bloggers Seth doesn't allow comments on his blog - probably due to the popularity of his blog, so he does have the final say, although he does allow trackbacks.

You can subscribe to the blog via email or RSS feed - and his brief regular posts are a perfect addition to your RSS reader.

Seth's blog easily makes it into the top ten must-read and most-read business blogs so subscribing is a no-brainer for anyone in business wanting to lift their game.
