I think the biggest problem holding back 3rd parties using the IoT/WoT data is that the old mental models for such data (like all the electric meters are read by the electric company and they send you a bill) is very centralized, so that's what we are seeing so far. The sensors are still feeding data to one central place and there's really no incentive to share that data besides directly with the customer.
What exactly am I going to do with the data my "things" collect? That question hasn't been answered yet, as far as I can tell. Once companies making "things" start answering this question in a compelling way, then I think lots of other "things" will follow a similar model and the space will flourish, so it's good to see the W3C getting some publicity on making things open before this happens.
I still have no intention of buying a "smart" or "Internet connected" thing besides computers, media devices (game consoles, chromecast, etc), and my phone. I'm sure others feel similarly, so what kind of product would convince me to change my stance?
The IoT and WoT (internet and web of - things), will probably be more than just that: a device with some sensor, inter-connected. I feel like the real question here is not what can you buy(as a consumer), to interconnect, but to what, can your device connect with.
A phone and a few taps on screen should be just about enough to do anything around our every-day life, and even better, no taps. We should be able to walk by and interact with services without even reaching for our phone.
