We have seen it on instagram, facebook and youtube. We need this implemented as a feature for invision.
This is becoming a vital part of social media with both facebook and youtube adopting it. With stories users blog their daily life without worrying about everyone seeing it or people looking at it more than once ect...It encourages users to check the site for live updates that they may miss if they decide to wait a week before logging back in. Users want to be able to make posts that only stay up for a day and self destruct, or that only select friends can see, when you give them this they will post more freely. It will also make your site look more complete by todays standards.
I doubt many invision communities will develop a decent Club section most could be considered clubs themselves, its a really cool feature but more emphasis needs to be put on user interaction and post engagement, maybe a friend system. I run a few facebook groups and I know how notoriously hard it can be on facebook I can't imagine clubs working for too many communities infact most are bare with one or two clubs, its a wasted feature. We need user interaction, better status updates, we need to change the way we post, there is things we could be improving on that would help us even the playing field.
+1 for Invision Stories
