NewsGator has an article about RSS that is worth a read,
First, let me get this out of the way – RSS use in the enterprise is definitely alive and well. But it’s not in the obvious places. No one is writing articles talking about how their desktop feed readers are revolutionizing the way they do business. No one is talking about how they’re retiring their Exchange servers because so much content is delivered via RSS instead of email (and in fact, email is alive and well). No one is saying “if I only had Google Reader behind my firewall, I could save millions of dollars.” Few companies even say their users are clamoring for some sort of enterprise RSS application.
There is a pretty good reason for this lack of clamor. Although Reinacker isn’t motivated to say so in this article, it’s important to remember that RSS, or Really Simple Syndication, is an XML Application, and as such, it was designed, as ALL XML applications are, to fulfill exactly this function. To quote Wikipedia,
The Extensible Markup Language (XML) is a general-purpose specification for creating custom markup languages. It is classified as an extensible language, because it allows the user to define the mark-up elements. XML’s purpose is to aid information systems in sharing structured data, especially via the Internet,  to encode documents, and to serialize data…
The takeaway from this is that RSS isn’t quite ready to replace email, but, it is proving that XML and it’s derivatives, including RSS, the new Microsoft OpenXML formats and the plethora of other XML based standards being used for data interchange, is truly an effective next-generation alternative.
The main thing holding these XML-based standards back from replacing email entirely is the sunk cost of development into what may soon be considered legacy email based systems. XML is simply capable of doing more with less, and as the power and functionality of XML formatted data focused clients improves, they will replace or transform business communication.
The day may sooner than later come when email-based communication will be something your Microsoft Outlook software does not include by default, but will only be available as a free add-on for ‘legacy-based’ systems.
Because, again, of the sunk cost of email development, that day may not come in the next four Quarters, but if the pace of RSS and XML based applications does not abate, it might not be long after that.
The first thing to look for may be conversion services that convert incoming email into your preferred format. Some of these exist already and I’ll cover them in a later blog.
Thanks for reading.
