Written by one of the smartest people in online marketing, Seth Godin: Memo to the very small
Basically, don't waste a lot of time on a fancy Web site. Instead, focus on making sure that you can be found by search engines and have a way of easily updating your site. E-commerce? Don't worry about it. Spend $5 a month on a nice Typepad blog with a professional look. Spend your time and effort on doing what you do best (making wine and building relationships).
Does Seth's advice apply to small wineries? What do you think?
