Models to follow, lives to inspire us, and names we must not forget to tackle stereotypes  pushing women away from science. While some names mentioned above belong to very bright and famous senior experts, one must not forget the amazing women leading and forming communities such Mitchell Baker  leading Mozilla, Cathy Casserly  as CEO of Creative Commons, Kat Walsh  as the Board Chair of Wikimedia, and all Global Voices Online female authors and editors, who make up a majority of our community. We should also remember those groups of women who are the custodians and guardians of traditional knowledge in all cultures.
Women have been at all times the keepers of culture, the depositories of knowledge and the seeds for the future. Lets honor all of them today.
