Brian Clark’s blog, Copyblogger, is one of the hottest on the Web. In less than a year on the scene, Brian has built up a subscriber base of more than 6,000 and is ranked in the top 900 blogs on Technorati.

How has he done it? And who is this man of mystery who describes himself only as “a serial entrepreneur, not a copywriter for hire”?

We’ll see if we can find out tomorrow night. On Thursday, Nov. 16, at 8 p.m. Central (9 Eastern and 6 Pacific for the time-zone challenged), we’re going to interview Brian on our debut show on BTR. What’s great is that you can listen live and call in to the show live to ask Brian questions.

The call-in number is 646-915-8556. Get all the details at www.blogtalkradio.com/mediaorchard.

We hate it when we don’t keep up with Pick of the Orchard. Would someone please tell our clients to stop bothering us?

Michael Arrington of TechCrunch will appear on BlogTalkRadio tonight at 8 p.m. Central to discuss the TechCrunch New York Party and other Web 2.0 matters. And because it’s BlogTalkRadio rather than a conventional podcast, you can call in to the show live. Get more details here.

Speaking of BTR, the company and its CEO, Alan Levy, were the subject of a just-published profile in .net magazine.

If you’d like to host your own BTR show, it’s totally free; sign up here.

If you’re not familiar with Pierce Mattie, it’s a well-respected New York PR firm that specializes in the business of beauty. They have a fun blog – and now, have decided to complement that blog with a live call-in show on BlogTalkRadio.

We missed their first show, but their second is today. The topic: Breast Implants 411, a Web site that shares information about breast augmentation surgery. The show’s at 3 p.m. Central. Go here to listen and ask questions of Steve Hultgren, Pierce Mattie and Edy Eliza.
