I remember reading a tweet about how memes can program our subconscious because our brain don't filter them (idk if it's true), and I thought about the idea of using memes to gather attention for a product/community/service, I believe this is the best way of advertising because people don't look at it as an advertisement, but rather as a source of entertainment
(I'm still researching this idea, and I would be open to hearing you guys opinion about it)
