Few points I haven't seen here

First tweet on this

Heading back to CBS46 Monday but going to be changes. Biggest one, this page will go dark Feb 1. Some will worry over this, don't. #trustme

don't. #trustme

Second tweet has the rebel alliance symbol added to it

/conspiracy poked around the Tzusday reference in Art of War, from page 21 (If Tzu 2/1 is the clue and not an odd typo)

"Therefore the skillful leader subdues the enemies troops without any fighting; he captures their cities without laying siege to them; he overthrows their kingdom without lengthy operations in the field"

And the two quotes of 'dark' in it as he's going dark.

Let your plans be dark and impenetrable as night, and when you move, fall like a thunderbolt.

All armies prefer high ground to low and sunny places to dark.

May be nothing. But like most things in pg, there's a lot of unusual coincidences.
