Expertise
I am not a professional astronomer by any means, but astronomy has been an interest of mine since childhood, and I am well-informed on the subject. If unable to answer someone`s question personally, I will know how to quickly find the answer online, because I keep myself informed about developments in the field and I know where to look for information.
Experience
I worked in an observatory for awhile at one point, doing various interesting things with a computer.
