This post from Unequally Yoked clued me in to Ada Lovelace Day, which seems like a day worth celebrating to me. You should check it out.
Ada Lovelace Day was launched in 2009 with a simple pledge on British civil action site, Pledgebank. Nearly 2,000 people signed up to blog about a woman in technology whom they admired on 24 March. The day was an astounding success, with contributors writing blog posts, newspaper columns and even a webcomic, Sydney Padua’s Thrilling Adventures of Lovelace and Babbage. The media covered Ada Lovelace Day with enthusiasm, including coverage from The Guardian, The Telegraph, the BBC and Computer Weekly amongst others.
