I get email.
I get a lot of email. Most of it is from people who have questions about astronomy; they heard about some event coming up, or some doomsday scenario, or just were wondering about something and want an answer.
It's hard to answer all the questions, but now I may not have to: I can send folks the Astronomy Stack Exchange, a user-driven Q&A site. It's actually set up in a clever fashion, where people can vote up or down on specific answers.
This site is based on the Stack Exchange sites, which are becoming very popular. For example, there's also a Skeptic Exchange, too! So if you have a question, you might want to check there first, and if it's not there, you can always submit it.
