Sure, I agree. But the problem is, what about the people who are on Reader to read about souffles? They don't want to read about quantum tunneling. But you sometimes post about both.
You're describing a distinction that exists on a service level now, that's basically arbitrary and inconsistent. With everything pushed to Plus and pulled back out of Plus, you can define not only social contexts like 'friends,' 'co-workers,' and 'family,' but also subject matter like 'souffles' and 'quantum tunneling.' This is a good thing.
N.B. I think this will only be truly useful if they add public circles as I describe earlier.
Based on the arguments presented here, I agree that using the contexts that users set up in G+ makes sense. Having said that, I think the part that isn't clear to everyone (well, myself anyway) is whether things will be "pulled back out of Plus". I really hope they will, but...
