Hacking Netflix has a cool idea using Yahoo Pipes, Netflix, and a PVR. Using your Netflix queue RSS feeds, it would be cool if movies being shown on cable could be recorded automatically from your Netflix queue, and removed afterwards so you don't have to rent them. The author mentions Yahoo pipes, a nice RSS mashup tool, but it's not totally necessary.
It's not currently possible, but it certainly seems doable, and something I'd use if it showed up on my TiVo.
The other thing worth sharing is "Beware the HDMI Scammers". It's about the proliferation of overpriced HDMI cables. A couple years ago, you could find a decent length of HDMI at many electronics places for maybe $50. Now, you'll often see them carrying prices of up to $300. I've heard that places like BestBuy carry cables that start at over $100. Even Radio Shack isn't immune to the greed -- my local store's cheapest cable was $69.
HDMI cables are all pretty much the same, it being a digital connection and all. You can find perfectly good cables in the $5-$20 range online at lots of places. Don't get snookered into overpriced cables the next time you buy a TV. Hold off and order them online for much less.
