Today Robert Scoble said something terribly trenchant about marketing: 

"You should be fired if you do a marketing site without an RSS feed."

He’s right. 

Really Simple Syndication (RSS) isn’t about blogs.  It isn’t about geeking out and being a blogger, either.  Forget blogs.  RSS is about giving your customers the ability to say "Yes, I’d like to continue to hear what you’ve got to say."  You’d have to be a total coward of a marketer not to try using a RSS feed (whether you call it a blog or not) to have a conversation with your customers.  It’ll take a bit of work, and you’re going to have to put some writing and thoughts and feelings out into the public domain and maybe take a risk or two, but that’s life. 

Good marketing takes guts.
