How does Plinky work?
Every day we provide a new prompt (like a question, or a challenge), and everyone gets a chance to answer.
It’s simple to add photos, maps, playlists and more. You can easily share your Plinky answers on Facebook, Twitter, Tumblr, and most major blogging services.
We know you’ve got something interesting to say. Plinky is here to help you say it in a fun and compelling way.
I guess it is for people that are bored.
