what about creating a social group on something you feel is fun then inviting your friends to join in. this way you will be able to talk about all the fun stuff you feel you are missing out on. there is also private messaging. this is where you and your friends can message each other to talk about fun things. there is also a game forum, social forums where you can also create threads and post about things you feel are fun.

you can also go through the process of becoming a chat leader and holding your own chat discussions on something if you dont see any chats on that issue.
