MASHABLE - Jan 26 - Lips, a new social network geared towards free sexual expression, aims to provide that space. Founder Annie Brown and her team want users - sex workers, erotic artists, queer people, activists, and more - to post without fear of censorship or harassment. It's a much-needed alternative to mainstream social networks that started to censor sexual content. Lips is created in the form of a progressive web app because it is more cost-effective than an iOS or Android app and they may not have gotten past the stores' approval processes.
