On Author Interviews

I'm sending e-mails right now to several different authors, trying to get them to answer me a few questions to post up here.

Have you ever done this before? If you have, does is take long for the author to get back to you?
I know I won't get an answer right away, authors are busy people, but who do you think could answer my e-mails?

I'll keep my fingers crossed!
I have some interesting questions for some of them. Hopefully I will at least have one of them answering me.

Cross your fingers for me, and you might look forward to some very cool new features!

Thanks,
