Hey Piotr! Yeah probably it's due to the fact that not so much advertising has been made so far.
I guess you've missed all my posts related to this campaign, because the 20th of February has been announced since a month now :-)
For many people one day to get prepared is unfurtunatelly very little.
Just copy paste a youtube link into your Twitter and Facebook account. Not sure why one would need more than a day of preparation to excecute that..? :-))
Have a great day, and would be cool to have you participating!
