[Note: Satuday and Sunday posts stray a little further afield from building effective winery Web sites.]
Copyblogger has a great "how I built traffic to my blog and Web site" post, which recounts how he used a free giveaway (the Viral Copy e-book) to build traffic. It one of a series of posts entitled Building Your Fan Club.
I think that online tools (Web sites, e-mail, blogs) offer wineries a great opportunity to connect with their "fans" (it's one of the original words we used to describe site visitors in The Winery Web Site Report). On the other hand, I know that you probably have too much to do already. So, I offer this up as a Saturday post for those with time and interest.
