Operational question here: when I read news with Google Reader, I star some things and I share some things. Often they are the same things, but not always. To me, the star means “This needs more attention later”, kind of like a “Next Action” in the GTD sense. Share put is in the public link blog. If I come back to one of these things and I subsequently blog it, I unstar it. Should I also “unshare” at that point or just leave everything always in there? I don’t have a real feel for what is useful to the people that might use this.
