Youtube's new terms of service will be applied on 10th December. That will result in the fall of many small and mid-sized Youtubers. They will be marginalized / demonetized / censored on the platform. You can read more about this in this article by The Verge.
Refer to "Sample Memes" in the last section of this blog to get some idea.
Theme: Promote 3Speak as a better alternative to conventional video sharing platforms like Youtube and Facebook. You can add references to the unique qualities of 3Speak and STEEM in your memes in a creative manner.
This contest will be followed later by a community driven task starting from 4th December. The top memes (from this competition) will be used by community members to attract the creators. Referrers will get big bonus rewards if they manage to on-board a major creator on 3Speak. We will be giving large delegations(100k SP Pool) to these creators as well. So it's a win win for all of us. More details on this will be shared in the subsequent blogs.
