Hi Tara,
I distribute RSS feeds on Casinofeed and they definately have a use – but the key to success is content. If they are constantly updating and offering up-to-date and relatively interesting information then they are possibly worth pursuing. Also, there are more marketing opportunities for RSS which expands the overall scope of exposure. However if it is content that rarely updates or of little interest, then its more trouble than its worth IMHO 
Cheers
Simmo!
