maybe you could even search other people's meme pools if they make them public. and if you use one of their memes to post, they get a small fee. Still saves them money because they don't have to post it to blockchain.
@4 random idea, what if users could to upload their own gifs, memes, etc, to the blockchain, store it as their own personal memes tab or something, and later they can reference them by pointing to them on blockchain instead of reposting them each time.
