Techweek Chicago is facing a barrage of criticism for using somewhat-sexy images of women to advertise a charity event, as the tech industry already faces scrutiny for its treatment of women. Techweek Chicago has apologized, saying they will host discussions about their promotions and diversity in tech. EDIT: Jacqui Cheng notes that Techweek should have learned their lesson six months ago when they were called out for having bikini models dance at their afterparty last year.
