I'm just getting my blog rolling at http://stuffandbits.wordpress.com but would also love to trade interviews. This is actually a very effective way to promote one another and is something that digital publicity professionals pitch ALL the time for clients.
When I'm not filling my blog with clothes, shoes, handmade goods, and other bits of content, I work as a social media marketing director for an agency in Los Angeles. That said, if anyone has any other questions about promoting your products or brand via social media, let me know! I'd be happy to answer them.
