The video creation bounty is already closed, so what will be the next bounty? I don't think this campaign is successful because a lot of videos is not good.
Why do you think so? My opinion is the opposite, that a large amount of video means that the team is trying to move the project forward and offers to look at the project, rather than read a large article.
Especially young people prefer to watch the video than to read the article. I think that a large number of videos on Youtube will raise interest in the event
