After half reading through accelerando> by Charlie Stross it occured to me that implementing a news agent similar to the agents in the novel would not be difficult at all.
So I am currently working on a framework for such an agent. The first part will be a source plugin that will be able to fetch "news" from a certain location (be that a blog, some news site, or a filesystem) and then a frontend for representing the results.
A middle part has yet to decide the grade of "interestingness" of each piece of gathered information. Again I toy with the idea of weighted buzz^Wkeywords defined by the user (me). I am not sure how well this will work out.
