This probably isn't news to anyone in the know, but I'm not a gamer and hadn't even heard of Orange Radio before today.
Orange Lounge Radio is an internet radio station dedicated to video games & the gamer lifestyle. We also present a weekly podcast with all the news and discussion that gamers really want to know.
They also provide a podcast feed above and beyond their 24/7 streaming.
Orange Radio is a great example of a subject area that can flourish on the Internet, but not so much in local geography. Yes there are tons of gamers, but how many of them meet and talk in real life instead of via a headset while playing? Podcasts like Orange Radio provide peer review of subject matter that might not otherwise be available.
I'm like that with blogging. I know a couple of casual bloggers in real life, but nobody major. All my peer support comes from online.
Where's your audience? Can you reach them better online? Perhaps bring them together and form some sort of community?
