Server logs of page hits provide less and less value in terms of knowing what people are doing (was it ever possible to truly tell bots apart from humans? to compensate for caching proxies run by organizations?), the more client-side and mobile apps we develop. I think that it's inevitable that any meaningful tracking will have to be done client-side. Looking for ways to adapt our URL schemes for the sake of server logs seems like rearranging the deck chairs on the titanic to me. We should be trying to put as little work into it as possible. Our stats efforts should be rather focused on more fine-grained client-side and mobile tracking, which is what we need to truly answer questions, even on our old "static" pages like the articles themselves. The same way that I've been working on tracking how long images are being viewed for at the Amsterdam hackathon in preparation for Erik Zachte's RFC on image views, we should be doing the same sort of measurements on articles.
