Author Interviews (extra contest entry)

First, I want to say please bear with me. I'm still new to all this blogging business, but I'm hoping to start doing author interviews soon. The only major, extremely daunting problem for me is how to get about doing it.

Sooo, I was wondering if I could get some help. I basically have two questions, one that requires some experience amd one that doesn't:

1. What author would you like to see interviewed?
2. When and how did you start interviewing? (ie. popularity of your blog, approach to the author)

If you answer, I'll love you forever and give you an extra entry to the contest! Any other advice is loved too. :)
