I'm going to make a huge leap and assume that most visitors to your winery Web site use Microsoft Internet Explorer 7 (IE7). If you have a winery blog, chances are that most of these visitors keep up with your blog by periodically visiting it to see if something's new (rather than subscribing to your feed).
I think it's important to get more of your winery Web site visitors used to the idea of subscribing to blogs. Feel free to point your visitors to this post, or improve upon it for yourself (you might even replace my screen shots with ones that feature your own winery blog). Please add a comment if you do.
Microsoft's Internet Explorer 7 comes with a handy "Feed" button. You may have seen it:
When you're on a page with an RSS feed, it changes color from gray to orange:
If you click the button, Internet Explorer will display the feed information, and offer you the chance to subscribe to it:
If you click that link, you'll be asked to confirm your choice:
Click "Subscribe" to subscribe to the feed. You'll get a message showing it worked:
The newly added feed will appear on the Feeds tab of your Favorites icon (the gold star):
A feed with new information will display in bold and the Feeds icon will change slightly (a little "gleam" highlight appears in the upper right corner) to show you that there's new information in one or more of your feeds.
Now you don't have to visit a blog every day to see if there are new posts. Just subscribe to its feed! You don't have to learn how to use a blog reader - it's part of IE7.
Note that feeds are not just for blog posts - RSS is intended as a general mechanism for notifying interested parties that new content is available. It's just that blog software like TypePad and WordPress produce RSS automatically.
