Incidentally, I found it somewhat amusing to discover that before executives started talking about "blue sky thinking", the term "blue sky" in a business context was primarily associated with fraudulent business ventures, which led to "blue sky laws" to protect investors.
I don't think Bluesky is a fraudulent venture, but I also don't think it is anymore imaginative than the modern use of the term in C-suites. It is simply business as usual -- blue sky, incorporated.
