I added something new to Reply to All from a company called madKast.  Check out the "Share" icon next to each entry title.  Click on it and you can share it or tag it in a variety of ways – a nice all in one way to keep up with all the various places it could go..  They are working hard in Boulder at TechStars and I received a nice note from Josh Larson (one of the founders) about trying it out.
