The title of this post is taken from a Saturday Night Live video (warning: offbeat humor, rap music). Here, it represents the fact that on Sundays I usually post material in which people might find odd (given the focus of this blog on winery Web sites).
Still, Bringing Your 'A' Game is worth a read (warning: slightly profane), because it points out that the Internet (and related technologies, like mobile phones) are a massive, powerful venue for near-instantaneous word-of-mouth about your product (both good and bad).
In the case of wine, think of it as The Wine Advocate/Spectator vs. hundreds (perhaps thousands) of wine blogs (i.e. customer reviews). There is an opportunity here that most wineries are unaware of: making sure your wines are known to (and talked about by) wine bloggers.
