Remember, RSS=Real Simple Syndication.
That is still unknown to a lot of people. AdSense for RSS is one such concept that should have great potential. I do not hear so much about it now.
Example:
You have Ad space for sale on your site and a company that sells products and services that fits to the content of your site. It may be valuable for them to have a minisite within your site, where content is syndycated through a RSS feed.
Note:
1. Your heading of this post is "Does RSS have a future in marketing?".
2. Your article in WebProNews has the following ingress (correct word?)
"RSS has been touted as a vehicle that could supplant email marketing; a skeptical look at RSS indicates what companies will need to avoid doing to make it work for them".
Yes indeed and make it much better, focused and reduce email spam.
