Well, that's a good idea. Do you plan to add more languages? And what's your business model? If everyone puts together their own personalized feed, you'll have to generate a separate podcast for each person. That could get expensive.
No plans for other languages at the moment. Right now my business model is to lose a bunch of money. The $5 plan might get close to breaking even. If it gets too expensive and I don't want to make a business I'll open source it all with instructions to install for those interested.
