Judging by the reviews of any quotations in the wordstream, the idea of advancing comes up - to enter the tower to hang the simplest tasks in higher mathematics or simple tests in Russian, until you pass - you do not enter. A knowledgeable person will immediately give an answer and schoolchildren should learn and do not kill their time by squeezing ratings and wordstream. Ideally, a very simple test with every update "dunk". Type the emphasis or insert the correct letter.
Pros: increased literacy of the population of the runet, partial reduction of dependence on the basha :)
Who liked the idea of a plus to get to the modes!
