Right around the time that people were (most recently) bitching about RSS, I had a meeting in regards to a new project where in the client wants to be able to send out a sort of "broadcast message" when they have a new document available for the public to consume.
The first thing that came to mind was that you're not going to "broadcast" anything unless the person you're sending the message to really wants this information (i.e. I'm not designing some sort of spam system!).
Secondly, besides having a plain old opt-in list, RSS might be of some use.
RSS gives us some extra opportunities with little (our feed on other sites) or no (users' aggregators) extra work. Is this a real world solution, or am I dreaming?
