Wikipedia for mathematicians 1: Why contribute?

Wikipedia is growing (somewhat more slowly, recently): 4.000.000+ articles (as of December 2012), of which about 28.000 are on mathematics. File:EnwikipediaArt.PNG

The better the articles get, the more experienced and knowledgeable writers it needs to improve them. The number of editors is declining. File:Enwp_retention_vs_active_editors.png

Wikipedia articles are highly visible: google queries on scientific topics typically show Wikipedia first: [http://www.google.de/search?q=whitney+stratification stratification] [http://www.google.de/search?q=sperners+lemma Sperner's lemma], [https://www.google.de/search?q=random+graph Random graphs].

Wikipedia writing is easy, fun, and also improves your writing skills.

Everybody, including you, is using Wikipedia, so sharing your knowledge will make it even better.
