As with Vine, I expect v2 to be the birthplace of many new culture-changing memes and jokes. It would be a cool idea if the staff at v2 kept track of what is going viral at certain points in time and made a timeline (or something else) to show what was popular during a certain month or year.
Vine did this during the end of it’s run. They made playlists covering certain memes/challenges that happened on the app. It would be cool if v2 did this from the beginning so we can see how much the app evolves.
