Nah, good on Buzz. In space/astronaut enthusiast circles, he's one of the popular astronauts, who's always out their in the public pushing space exploration. Buzz has had a lot of personal hurdles since Apollo 11 and he seems to not take his fame to seriously, albeit he does make the most of it, which I think he has every right to do so.
I go by the theory that the Apollo Astronauts are genuine heros, and he is one of only 12 humans who have walked on the another world, AND most , if not all of them, will not be with us in another 20 years time, so they need to make the most of their time, and if that means trying different mediums to put their message across, good on them.
