A RSS feed is no longer a luxury add on, it is a necessity!The new IE browser will have a RSS reader, FireFox already does. We need it now.
Look at all the "Partner Sites" that this site sends RSS feeds to:
http://equipmentsellersusa.com/searchresults.phpand it's just a used tractor site.
I subscribe to the RSS feed from ecusb.com. RSS feeds are very useful for users and really help promote your site.
