I actually think this feature will be pretty useful.
The (home) feed is for everyone to interact regardless of their preferences lolz but a club is only focused on one thing.
I guess we could also have badges on our profile, somewhere below our roles, to show that we are part of a specific club. Or have the option to show or not the club to other people visiting your profile :D
No I disagree. I think you should be very careful to further segregate an already very sparse community.
I understand your point but I think that the only thing that would segregate the MDL community would be if they decided to make it available in multiple languages (that happened to Viki; however Viki is a paying platform so it is a bit different). It would also segregate MDL if you would be able to hide certain countries as to not have access to them.
But clubs would be for fun, just like the feed. Users would be able to send invitations, make banners, contests etc.
I have been doing this with the friends only option in some of my feeds so as to not intrude on the public feed. But clubs would be cool, I do like the main feed it lets me see things i would not normally look at.
I don't know about badges. I've always found them pretty meaningless. I love the idea of clubs though. I don't really see how they would segregate MDL. Clubs would allow users to meet more people who have similar tastes to each other.
