There are some great lessons for wineries in this post, entitled The Shop I Want.
We’re in a world where you can find anything you want, which is great, except when you realize there’s a lot of everything...The shop I want is full of people who are dedicated to their opinion. Who are happier understanding a thing rather than wanting it. These people will happily tell the story of [how they] happened upon this opinion and I want to hear it because the opinion of someone I trust is just as valuable as my own.
He goes on to talk about Twitter as (one example of) a source for opinions about stuff.
There are some great thought-starters here for those who are willing to ponder a bit. We live in a world full of wines. We're looking for opinions with stories behind them.
We are all suckers for a good story.
(PS - When you find a blog post that's interesting, don't forget to read the comments as well. In general, comments are at least as valuable as the original post. It's where you see what the author missed, for one reason or another, and get the insights of other smart people.)
