Great Minds Think Alike?
AG, I've been working on the same idea (well, somewhat; I was going to actually post the clips) for several months now. The only problem with your idea is the same problem Ann alluded to: people will be upset if/when they can't reach clips because a producer's site is down or because the producer switched the clips on its site, and they will take it out on you. Sure, you could verify links every day and all, but we're all human, and I imagine you're bound to slip up once or twice.
The hardest part of all this is to find web space. If you can find some, please, let me know. Those free sites have such small limits on bandwidth 🙁
