diagrammes modernes was a bit of an orphan site for me. Traffic was low, mostly because my posting was sporadic. The Theatre of Noise already displays schizoid tendencies, so why not add another personality? If you are only interested in development posts, you can access them using the /dev category. And soon there will be separate feeds per category, further streamlining your experience.
In order to make room for that new category I have folded Politics (which included economics) into Media, which has now become something of a catch-all category for arts, culture and so on. Maybe I will rename it.
