So this is in all probability the result of too much time on my hands, but here goes anyway.
So we all know Pompeo’s tweets have been on a schedule. It made me think of a military drum march. So far today his tweets were:
7,7:30,8,8:30,9,930 (6 long)
10,10:15,10:30 (3 short)
11,11:30,12,12:30,1 (5 long)
Then a pause until 2. (EDIT: times above are in CST, add one hour for EST)
So I started playing a snare drum in my head to the rhythm above and it seems so familiar. This video below is the closest I could find, but still not exactly what I remember. https://www.youtube.com/watch?v=Hb72p4afYbo
It might also be Morse code, but I cannot see any message. Or it might be all nothing. Just thought I would post and see what others came up with.
You can set up tweets ahead of time to be posted at set future times. Perhaps Pompeo is busy with something else and did those scheduled posts just to keep people from noticing he's not really online.
