A nice article from Lockergnome titled The RSS Enterprise Market Overview talks about the promise of RSS in the enterprise.
Chris summarizes the benefits for the enterprise
a] Direct mass communication with employees, on either a mass level or also employing personalization and customization to make sure only the most relevant messages are distributed to the right people.
b] Measuring and watching buzz about the company, its brands and products.
c] Filtering industry news for relevancy and making it available to appropriate teams and employees in need of specific content.
d] Targeted and secure in-house communications between employees and teams, which also includes project collaboration.
Other applications that usually aren’t discussed under the enterprise RSS umbrella, but probably should be in order to maximize the impact of RSS, should also include:
a] External RSS feed publishing in order to communicate with prospects, customers, business partners, the media and other target audiences.
b] Republishing syndicated content on corporate sites in order to easily display focused industry news from multiple sources.
c] RSS advertising, which in the context of enterprise RSS would especially mean ad campaign management capabilities.
For all those folks sending out newsletters, please use feeds, I am not going to subscribe to any more newsletters, its not practical and it fills up my mailbox.
