Spending a rainy day exploring my new KDE4 installation, I find I have something called Nepomuk available and running. Googling for this, it seems it's something to do with a "semantic desktop"(?) but apart from a lot of management-style gobbledegook (in the style I heard more than enough of in my many years with British Telecom) I can't find much about how (or more importantly, WHY) I should use it. Apparently it integrates into Dolphin, which I don't use any more than I used Konqueror, as I can do the sort of things these applications do most effectively and quickly at the command line.
So what benefits does Nepomuk offer me and how do I use it? I don't like to dismiss new things out-of-had, but I'm struggling to find any point to it.
