Welcome to DrunkWallA d̶i̶f̶f̶e̶r̶e̶n̶t drunk kind of social network.
Not sure why I am here but I certainly don't want to read...let me draw on something
Time-based
New walls get created weekly (just in time for the weekend) and who shows up on page one is the same as the first person to happen upon the new wall.
Limit Interactions
Each week you get two 6-packs (make it a game by coordinating your comments with the consumption of a beer) of drinks which are spent to interact with the wall. Make them count!
You can spend one beer on writing on a section of a wall or two beers to type out a note on a section of the wall. If you are feeling artistic try working on a few sections of wall together, but watch out some drunk person might ruin your work... or make it better!
Globally Distributed with Multi-Language Support
Everyone should be able to share on any wall they come across in any language they choose... who invited that guy to the party? There are also walls in every state so people can rage about sports teams and such.
