I joined a women in tech group in college when I started Computer Science. I was super excited and sincerely believed in the cause and I threw myself into it 100%. By the end of the semester, what had I accomplished, really? I had made countless posters and pink ribbons and cutesy giveaways for our school fair booth and what felt like zero progress on making things better for women in tech. Instead, it was just a monthly meeting where we patted each other on the back without really doing anything.
I'm sure there are groups out there that accomplish real and admirable things but I think it's far too easy to fall into just self-congratulating each other and approaching all the wrong issues.
