Productivity...Part 2....Online

I read this interesting article here, that is actually a book review of a book about how to be smart with your time online.  As I mentioned previously (here), I don't know if productivity is helpful to all people.  This review says that the biggest advice that the Net Smart: How to Thrive Online by Howard Rheingold gives is to really plan out what you are going to do online when you get on.  This is hard to think about practically for me because I am influenced by what I see--I will go to someone's blog post because they posted and I happened to see it.  Or I will read an article that I happened to see on Twitter etc.  But I like the idea in theory. So...how would you go about planning your online adventures each day?
