"As Wikipedia founder Jim Wales revealed, back in 2005, 50 percent of all Wikipedia edits were made by just 0.7 percent of users; 75 percent of all articles were written by less than 2 percent of the user base. These numbers reveal that the active Wikipedia community is a lot smaller than you might think. It's understandable, then, for this active group to be somewhat self-centered, and not always accommodating to new or casual users."
