Here's what we learnt

 
(*when Twitter CEO Jack Dorsey, 41, and Facebook COO Sheryl 'Lean In' Sandberg, 49 were grilled last week about election interference and data protection)

Sandberg and Dorsey were as slippery as the politicians asking the questions       
 
Coming from an industry that moves fast and breaks things, both were sorry for being so hopelessly slow to fix things, giving highly pre-prepared answers that appeared to lack meaning beyond lip service.  
 
Dorsey, worth $6.2bn, at least made one honest confession... 
 
He said: "I believe if you went through our rules today and sat down with a cup of coffee, you wouldn’t be able to understand them", adding: "We haven’t done a good job of that in the past", while Sandberg, worth £1.6bn, kicked most difficult questions into the long legal grass. 

...and looked more sartorially interesting 
 
His open collar, long beard and nose ring gave him a "Civil War Boho sensibility", according to The Atlantic. He even tweeted his heart rate during the day’s testimony, which peaked at 109 - impressive for anyone being grilled by government.  
  
The real drama occurred in the corridor outside, courtesy of the nastiest man in American  

Conspiracy theorist Alex Jones, 44, who claims the Sandy Hook massacre was faked, verbally abused both 2016 Republican presidential candidate Marco Rubio (watch the extraordinary "don't touch me" moment here), as well as CNN reporter Oliver Darcy.  

You're more likely to be banned from Twitter if the CEO eyeballs you in person 
 
Jones had sat in the front row of the proceedings all day and was only later permanently banned from Twitter by Dorsey for "past violations" and "abusive behaviour", making Twitter the last social media platform to "de-platform" him. Srsly.
  
The stock market wasn't impressed with Jack or Sheryl's performance  

Twitter shares dropped 6% after Dorsey's appearance and Facebook's shares ended $9 down at $160.


Google, showing utter contempt for government, didn't even both showing up  

Its founder Larry Page and CEO Sundar Pichai proved they were beyond governing. Capitol Hill was incandescent, with one Senator, Tom Cotton, subsequently accusing the global search engine of being in bed with the "Chinese Communist Party". An empty chair was pertinently left on display.  


The public care even less 

By the end of the three-hour Senate hearing on Wednesday, more than half of the seats in the public gallery were empty. Google called it right.  


PS If you don't really care either but find Twitter's advertising annoying, here's how to block 1,000 Twitter advertisers in one fell swoop
