It can be difficult finding a subject for discussion that everyone can join in on with 7 different people, hence weather, travel, politics, conspiracy theories and possums.
The only disappointing thing for me was I didn't feel I got to know everyone that well. When I met up with tickle dude au and zaif666 we shared a lot of our interests and hobbies, but for the group gathering no one talked a good deal about themselves. I hope no one was put off by the experience; it just seems some things are harder when it comes to groups.
