I suggest you recheck the SEC status of using social media, like facebook for investor updates
"Since Facebook is not the legally recognized communications channel for SEC-compliant news releases,"
As it is now accepted by the SEC in leu of 8-K fillings thanks to NetFlix and the SEC approval of the use of social media....in 2013.
It is also accpetable in leu of PRs to use social media for non SEC required updates to investors. Not every change in a company requires an SEC update, nor is every change in a company insider info just because it has not been released in an SEC 8-K. Most changes in companies do not require any SEC update. For example, Amin's departure from MVTG was not an SEC event, as he was not a director. His departure was know the day it happened by anyone (like me) watching his Linkden profile.
In fact if another huge $$$$$$$-BP-operation explodes again, you can bet it will be all over social media, and public long before the 8-K is filed.
