Maybe they mean "execution" as opposed to "ideas as questions"? Or maybe not: I guess it's true that even with PageRank designed and implemented, it's a hell of a long way from a business, with many opportunities to mis-execute. To go from the idea of pagerank, to a working pagerank is also a lot of work. Edison's comment about 1% inspiration, 99% perspiration applies both to inventing and commercializing. For myself, the inspiration of a product was instantaneous; the first working version took two hours; but it took a year of further iteration before my first sale. I think that's much more than 99% perspiration (though there were lots of little ideas along the way, and one brilliant suggestion of what to look at - from someone else - that changed everything). I think pinning people down on what they mean by "idea" might clarify things.
