Ok... this isn't *directly* relevent to your presentation, but it did twig a thought...
I read a lot of online newspapers, subscribe to a lot (too many!) RSS feeds, and have a huge list of sites I try to keep up with.
In my perfect world, I'd have a system that could do a content / context scan of all this raw data, and present me with just the stuff I'm particularly interested in.
I'd write the Parse::MeaningFromText and Mind::Read::MyInterests, but (what with all the reading I'm doing) I just don't have the time.... :-)
