Working on articles by friends and colleagues of mine is one of my favorite activities when it comes to Wikipedia, so it's nice to be able to contribute to improve one another's articles.
I recently nominated my beloved Louise Nevelson for good article. She's one of the most important figures in American art history, and is considered a forerunner of the feminist art movement. She identified as an artist, not a female artist. She was also sexually very free spirited, a fashion icon, and quite the character....and of course one hell of an artist. One of my favorite parts of the article is that when Alice Neel asked Nevelson why she dressed so amazingly, Nevelson replied "fucking dear..fucking." <3 sexually empowered people!
I noticed I have actually rewritten all of these articles, not actually written them (I've written plenty, whatever!)... I rewrote the Woman's Building article, which was originally started by a woman who participated in it... http://en.wikipedia.org/wiki/Woman%27s_Building (it needed work).
