We love GroupMe. We use it almost daily. It's our favourite way of avoiding SMS, coordinating the team, braving CES and exchanging childish jokes. Today, a new version drops, and it's bigger and prettier than ever.
The emphasis in GroupMe 4.0 is clearly to look more like Facebook and Pinterest, and everything else that's Internet Cool.
Photos and avatars are huge, chat streams are simplified and clean, and there's a newsfeed to catch up on group messages you've missed.
It's also available on iPad too, meaning that between iMessage and this, you've got one very nice mobile messaging command centre in your bag at all times.
