Social networking has gotten a lot of buzz lately from sites like MySpace, Flickr, LinkedIn, Friendster, and so on. The idea is that you probably have something in common with people who have something in common with people you already know.
Not to be outdone, the wine community now has its own social networking site: Cork'd ("The simple way to review and share wine"). Take a quick look at the Cork'd home page to get a better understanding of what this site offers.
Of course, you already have a community of fans for your wines. Cork'd provides a tool for them to share their interest in your wines and involve others who may not be acquainted. You might want to think about making sure that your wines are listed. And you don't necessarily have to do it yourself - enlist a fan!
At the very least, you might want to mention Cork'd to your newsletter subscribers - some of them may think it's cool.
