en:Did You Know - The reason that Did You Know articles are given points here is because its a great project and its a good way of checking and improving the quality of an article. However we are quite willing to give contestants 7 points if they can just get another experienced editor to agree on the talk page that the article is in line with DYK rules. i.e. You don't need to get on the front page to get the points. That is your choice. We believe the real value will be in creating a place where augmented reality apps work really well and seeing "your?" article on a glass plaque on the side of a notable building. More details follow.
