I have already in other sessions mentioned some ideas about memes and how they can be used in a variety of interesting ways. Memes can store value and can be a pedagogical tool.
Here, the idea is to use a regular hoarding board to display memes. Images, videos. The tweak is that they are constantly displaying memes created by the general population! The best memes are displayed randomly, and the creators are rewarded fairly for the fitness of their memes! There should be a cut-off 'number' of memes displayed within a certain time frame. It can be optimized as more data is gathered. Should not take long to figure out.
Memes are catchy and very economical in terms of attention span. They grab and let go of our attention in a concise time. Memes are in fact a bag of ideas that contains other ideas, and they can be perfectly fitted for short periods. You're running late for the office and you're using hoarding boards as your landmarks as you rush through the crowd to the station on time. You see a meme on the hoarding board as you rush, and you laugh at the meme.
The point is: everyone's in a hurry, and if you can create a funny meme that makes people smile and connect different ideas in their short, redundant times, your meme has real value!
This should be easy. We can use hashtags, to start with. We can also use a login-based competition where anyone, from anywhere, post their memes.
Which format of content?
It is also a matter of choice. It is up to the developers and users: it could be a photo, video, text?
