A push occurred today that enables you to vote on the video playing, and acquire karma.
Eventually there will be two types of karma, "room specific" and "sitewide".
Room specific is just your karma you've collected in that specific room.
Sitewide is just a total amount of karma you've collected from all the rooms (to be implemented later)
We aren't sure what else to do with karma yet, but it will be nice to have if that day ever comes. If you can think of anything let us know. Regardless of karma, it is nice to have the indicators if the video is liked or not.
