Cheering for the bureaucrats
When it comes to adoption of XBRL, I'm in the same corner as the reglators at the FDIC and other government agencies. A Reuters article cites some interesting applications that agencies want to apply XBRL including money laundering and environmental analysis.
To me, this seems like a very promising technology to automate and standardize corporate reporting. If it became widespread, you can imagine some interesting automated investment strategies based on interpreting XBRL data. It seems unclear whether this will get enough support to take off, but it does have some of the right backers.
