STEEM Price up 127% Today?!? What Did I Miss?

I go away for one day and STEEM prices jump over 127%! What happened?  

 There is a serious run on STEEM. What did I miss? 

• Did Dan come back? 
• Did Argentina suddenly decide to adopt STEEM as its national currency? 
• Did a lottery winner ask for their winnings in STEEM? 

What the heck?    

…not that I am complaining. I have been shifting from Steem Dollars to STEEM over the past few weeks, so this is really nice. But what has precipitated this Christmas-come-early turnaround? I know there are a lot of smart analyst-type people out there. What say you?
