One of my accounts was contacted by a Google+ community manager asking me whether I'd like to make a Collection that would be featured on the front of G+ Collections. Although I heard about Collections I never really bothered setting one up. It looks like a manual effort. You have to navigate to a specific Collection and make a post there apparently. It doesn't look like you can take older posts and move them to a Collection, or can you?
Has anyone here bothered with a Collection?
