Regarding the tagline, as @decentralion said in a call recently, often the best ideas come from what the intuitive misunderstanding of the thing is vs the rationalized over analyzed version. For the tagline we want something that is intuitive and sticks. It should be an idea virus that spreads. It should be contagious: something people instantly “get” when they hear it and then want to tell their friends. It doesn’t have to be super specific, it just has to make people want to know more 
What’s the context for the question here? Are you asking if it was a good idea to create a Meme ideas post separate from the tagline post? If so, then yeah I think that’s an awesome idea.
