@RickiTarr Historically, I would say "SharePoint", but over time, between companies no longer having a dedicated person or team doing web design for their intranet site(s) and the rise of WordPress exploits followed by WordPress instability, AND teams and OneDrive being set up to store files there (in the loosest, most simplified sense) it's kind of filling a hole that has been left by lots of bad decisions in lots of boardrooms across most of capitalism in the last decade, making it something of an actual, potentially usable "solution" now.
The next thing that comes to mind would be "Blockchain", but that's newer and less likely to be in my thoughts at all, generally speaking, since it didn't even occur to me until I was done typing the above stuff.
