Wiki Becomes a Way of Life: "Wikipedia, the online encyclopedia, has 490,000 articlesin English alone. All together, including its French, German, Italian, Chinese, Spanish and many other versions, it has well over 1.3 million entries.
"But without its 16,000 contributors, Wikipedia would be about as useful as a moldy 1978 edition of Encyclopedia Americana. With them, Wikipedia has become the world's largest effort of its kind, and one that is compared to Encyclopedia Britannica in terms of quality and breadth.
"Among those 16,000 contributors, there are some whose involvement goes far beyond the call of duty. These are the hard-core Wikipedians who spend long hours writing articles, or tweaking existing ones."
