I'm wondering about the initiative I'm participating in right now. I came here via a blogad at Daily Kos, and based on the limited number of questions I see posted on your blog, I'm wondering: * how many blog communities carried your ad; * can you name a few of the prominent and not so prominent sites; * why did you choose blogs to promote PBS Engage; * is PBS Engage being promoted anywhere else? I'm a bit stunned at the small number of questions being asked, relative to the stature of PBS in American broadcasting. While PBS Engage has only been around since October 2007, can you give us a noteable example of how the interaction here has affected the PBS viewer's experience?
