Nordstrom recently implemented use of RSS feeds, as part of the search process within their multichannel retail website.
Give this a try: Visit the Nordstrom website. Search for a shoe brand, like Donald J Pliner. You'll notice a little RSS button halfway down the page, on the right side of the screen. Click on the image, and you will be taken to a page that allows you to subscribe to the feed for this brand, using several popular feed readers. You'll receive updates as new styles become available.
This is an interesting take on the implementation of RSS within the multichannel retail community. Did the Nordstrom Marketing folks do this well, or should they have attempted a different strategy? Your thoughts?
P.S.: In the spirit of full disclosure, I worked at Nordstrom from January 2001 to March 2007.
