Poke Me (You know you want to!) (jpg)
The poke feature is intended to be a poke gesture (similar to "nudge" in instant messaging) to attract the attention of another user. Many Facebook users use this feature to attract attention or say "hello" to their friends. A previous version of Facebook's FAQ gave additional insight into the origin of the feature, stating: "When we created the poke, we thought it would be cool to have a feature without any specific purpose. People interpret the poke in many different ways, and we encourage you to come up with your own meanings." Mark Zuckerberg during a live Facebook webinar. There are several applications on Facebook which extend the idea of the poke feature by allowing users to perform other actions to their friends—such as "kick" or "wave to". People often reciprocate pokes back and forth until one side gives up, an event known as a "Poke War".
