That promised biweekly update went smooth, great job electroneum team! 
The last update on Facebook was on the 20 January at 15:03.
I agree they have not followed exactly what they said they would, but there have been regular updates on Facebook!
Looking at the definition of 'biweekly' you can see, it means every two weeks (14 days).
Today is January 28th, that's only 8 days since their last update on facebook (January 20th).
So as long as the next update happens between now and February 3rd they're all good, right?
They got one out early - what will be do ;-)
