I did a search, and while there was one mention of Open Sky in a thread on knives, there doesn't appear to be any other discussion of this anywhere else. So here goes.
This is a really dangerous site -- in the best possible way.

Different experts offer products they very much like to the folks who are following them. The products are often offered at a significant discount (for example, a D'Artagnan foie gras basket offered by Michael Ruhlman a few days ago was about 30% cheaper than it was on the D'Artagnan site). I didn't buy that, but I did get a set of washable clothes from Ruhlman that he designed for straining broths and other things that need to be strained.
So not just food, but loads of gadgets, too.
The nice thing is that, even if you aren't following someone, you can scan all the current offerings and then decide to follow someone if it's a very interesting item.
I just bought hot chocolate mix from Jacques Torres, and I also just "followed" the newest member of the Open Sky team, Rick Bayless. So far, I've gotten three things, and they were shipped swiftly, carefully packed, were just as represented, and were great. And I'm looking forward to getting the Jacques Torres hot chocolate mix.

But let us know what you're finding that you think is cool. I don't think anyone can look at all the offerings every day, so it would be good to find out what others are delighting in.
