People who are genuinely interested in memes will simply stick to Reddit/9Gag/w.e,
This is where we expect something different : while most of the memes today are on these platforms, you get absolutely nothing from it.
We're creating a platform that pays them for their content & time so we are working towards making these people join us.
Everything needs to start somewhere

The business model is based on sponsored posts to reward our users, but from our side we take a % of the investments on memes and will have a premium subscription like 9gag.

The idea here is to create a better and a fair rewarding platform based on memes, as the users are the one creating the platform thus getting incentivized.
Got to say I'm with AdolfinWolf here. I occassionally spend an hour or two when I refuse to get out of bed, surf for stupid timewasters like memes and I stick to the same old sites I always have.
You see the problem with incentivised platforms is that people are in it for the gains, and then they find ways to game the system, and then eventually you get a whole load of content that's just fake, or of poor quality, just voted or rising to the top, because they're made by guys who want those incentives. You can see the difference between a hot/trending list on Steemit vs hot/trending on Reddit, for example. Vast difference.
Besides, people can tip meme creators on Reddit.
The ultimate reward, dare I say, for meme creators is viral fame. No different with Bitcoin memes.
