Now We Have Some Questions for You

You guys give us lots of great story ideas—too many to answer them all. So I'm going to toss out some reader-submitted questions to the audience every now and again. If you know the answer, weigh in!
What's the most money anyone ever spent on a domain name? * Is it true that the X-ray conveyor belt at the airport can harm your film? I'm 16 and only remember using digital cameras, but my uncle told me you can't let airport security X-ray your film camera because your film will be exposed. Any truth to that, either now or back in the day? * Does iTunes have an all-time best-seller list? I wonder what the best-selling song is. Or album. Or TV episode. * Could you explain what the Salvation Army does? I've donated clothes to them for years but never stopped to think what it was. Is there a General? Is there a connection to the Armed Forces?
Have at it!
