I had a solid hit of viability listening to some Internet radio shows this morning. I linked through from an inspirational email to Hayhouse Radio and listened to some pretty solid motivational/spiritual content. Then, I picked up on the fact that the provider was wsRadio.com and began listening to an SEO Radio show about search engine optimization. All the wsRadio.com shows seem to be well implemented via an Active X player that worked fine on the Mac and each program is nicely supported by RSS feeds to promote return listeners. Professional quality. Well done. And, a welcome addition to the broadcasting landscape. On-demand radio will ultimately rule.
