It hit me :
I have been thinking about unification of blogging, wikis, email, bugreports, and all types of data about your software into on format.
It should be possible to just create a set of RDF files that contain all relevant information, these files will be just interpreted by various agents for display.
You can post the data that is directed at a specific person into a directory, for example if you want to send a mail to someone, you would sign that in an encypted rdf file and post that on your webserver. They would just pull it from your server.
In any case, this is making sense to me, it will be a central way to manage the publication on all the mediums needed. By using RDF you can mark up your messages with all the metadata needed.
The rendering can be done by a set of filters.
Imagine an wordnetization, ispellification of your text, identify the words etc.
That would allow for grammar engines to process your text easier... crazy idea are exploding in my mind...
