I like radio, listen to talk radio, have done my own podcast, interned at a crappy mean talk radio show and done my own internet radio show (to contrast all those "accomplishments," I don't have a paying job). While all the advice previously was about the depth of the topic and how to mediate the continuing trolls (something Jez editors could at least try to help with), I'm gonna throw out some unsolicited media advice.
If you don't already know the show or station you've been asked to interview with, google (or have your friends here) the shit out of it. Straight news or bias? Not that bias would be bad, but to have an idea which way the wind will be blowing.
You also can ask the interviewer beforehand what he/she'd like to focus on. Are you there to add to a greater conversation about Miley Cyrus's shenanigans or to bounce off that to the white/black feminist discussion? Knowing the station/show will also help this.
Wherever you're doing the interview (skype, ISDN remote, guy with a tape recorder in your house, in a studio, etc.), bring a friend. If you're being interviewed remotely, this can help you visualize talking to someone who knows you and supports you. As you know, friends are awesome and can help normalize this weird situation.
Interviewer style. This takes one or two listens or blog posts readings about previous interviews. Does the person do straight-on interviews ("Just the facts, mam") or more Devil's Advocate style?
My split second opinion is that it'll be a mildly in-depth interview about exactly what you've written about and the reaction to it. It'll be more about your initial article than anything you've experience in the troll woods. The audience will be friendly and more interested and inquisitive than judgmental and reactionary. You're being recorded so it'll be cut down for time and clarity and included into a larger segment about the Cyrus performance being weird. YOU'RE not the interviewer so you shouldn't have to do too much deep thought and let them guide you. Know what's important for you to get through and the rest should go smoothly.
Re: money and jobs, this can help you so PLUG AWAY! Plug your blog and other blog friends who you feel have helped you. If nothing else, it could provide ad revenue. Plus this shit goes on a CV! You could be a panelist for topics like this at a school or conference. I don't know what jobs you're applying to right now but this WILL help you in the future.
If you're feeling REALLY weird and crappy about the attention do this: think of the other bloggers and commenters you've been influenced by and have participated in this subject who AREN'T being interviewed or have +a million hits and DO IT FOR THEM. This brings you attention but it also brings attention and views and ad rev to all of them.
You're a wonderful, involved and gracious woman. This is awesome. It is weird and nerve racking but still AWESOME! And yeah, see if you can get someone to help with moderating the comments. If there's not an automatic way to do it, contact Laura (who seems to be in GT's corner) on finding a way to do it.
