@Rebecca_Thomson just alerted me to some blog posts about a session at the OpenTech conference held this Saturday where Suw Charman-Anderson and others reported back on the success of Ada Lovelace Day and other women in tech initiatives. Worth a visit:
Judith Townend: Where are the women in tech?
Kathryn Corrick: Finding Ada at OpenTech 2009
(includes a list of living female tech role models)
