I have written about Eric Sink on this blog a couple of times before, but it's time to do it again.

Eric runs a successful software company called SourceGear, who have a professional source control product called Vault. He writes a regular column for MSDN called the Business of Software, and on his personal blog is now posting his take on the 22 Immutable Laws of Marketing.

If you are at all interested in the business side of the software industry, read Eric Sink. As soon as possible.
