Very interesting!<p>I am currently building an RSS aggregator, too. Mine is little more complex, though - I wanna be able to rate items as interesting or boring and use some kind of filter (currently, a simple Bayesian classifier, I intend to replace or at least enhance with something more sophisticated over the holidays) to weed out news that I am not interested in.<p>The biggest problem is that web design is not my strong suite (to put it mildly), so the thing looks pretty ugly. Classification does not work very well, yet, but I am not sure if this is because the classifier sucks in general or if my training set is too small at the moment (I&#x27;ve only been using the thing for a couple of days now).<p>Anyway, it is quite interesting to see another approach to the problem.
