I keep reading all these horror stories about women being treated badly at technical conferences. I haven't seen a lot of positive stories. I think the conferences that are doing a good job need some recognition. That's why I've made a list of presentations being given by women at the next Usenix LISA conference. Conferences that are doing a good job of inclusion need to be highlighted.
This year the conference is in Washington D.C., Nov 3-8.
The reason you don't hear about conferences that do not make women feel uncomfortable is that it isn't a story. People behaving decently should never be a story, but that leaves us with bias. Good of you to point out places where professionals are behaving professionally though!
