December 24 (according to foreign media reports), users may find a letter to readers written by its founder Jimmy Wales on the website when they log in to the Wikipedia site. The letter requests users to make donations for Wikipedia. Wikipedia has been raising funds for a long time, but it is the first time that Wales himself has appealed to users to make donations. Taking into account the general background of the global economic downturn, the letter can not help but make people suspect whether Wikipedia is facing a survival crisis. (Translated/Guanhai)
