TECH CRUNCH - Mar 1 - Aimed exclusively at lesbians, bisexual and/or bi-curious women, the Dattch dating app is now launching in SF. The app emphasises photos, and thus draws comparisons with Pinterest in user interface. Dattch does not emphasise proximity-based social networking. It incorporates Facebook Connect and makes a point of weeding out fake profiles created by straight men. Dattch targeted London and other UK cities initially. Australia is also on its roadmap. The mostly female team has closed a $160K Angel round.
