Oops he hasn't updated yet!
OK good I was getting worried there
Oh no where is he again?
OK forreal Zach I am getting a little worried
Oh there you are, DON'T DO THAT AGAIN
WAIT, why didn't you update it?
There it is!
Here is where I began to get REALLY worried
WHERE ARE YOU JD!?!
HELLO HELLO ANYONE HOME?!
There you are!!
He seemed to take a little break here, perhaps he was hanging out with Donald and was having too much fun to update?
OK good he is back.
Conclusion: Zach loves his twitter followers.
Side note: Based on this data I have concluded that it is in fact him updating it and not a bot since it seems to be happening at random intervals.
