Consider the needs of your Internet visitor first. Will he/she benefit from the feed? If so, then feed away.
As an SEO advantage, because most of these feeds are broadcasted in several places simultaneously, they don't really count as your own unique content and thus aid little in increasing the importance of the web page.
I have recently analysed a site with an expert collegue. He considered RSS feeds to be excellent for SEO optimisation although he did not know how it could be done. Does anyone here known how to optimise RSS?
