If there is a will, there is a Poke. Poke gives you the ability to instill laughter upon your friends, frantically irritate your mom into bringing you food, or wake up your bestie from their 6 month coma while they come late to meet you for coffee for the 1000th time. Its a simple, fun way to say "hello", or "I Miss You", or "that dude smells like cat litter."
Don't live in a house full of cats, Poke your friends.
The ability to poke a contact whom you have added.
The ability customize your avatar and username.
The ability to play silly/witty pokes from anywhere in the world.
