poke on facebook it is a function of the social network that serves the person get the attention of your friends. The nudge on facebook is meant to say "Hey, I'm here!" or "Hi, how are you?" On many occasions poking on Facebook is a way of flirt with another person.
Poking on facebook started as “poke”, which means poke in English, so network users can poke each other, as a way to interact and have fun with friends and acquaintances. Poking on facebook doesn't have any specific functionality, everyone can do it whenever they want and with the objective they want.
People can interpret the nudge in many different ways, but mainly to attract the attention, get in the way of what some are doing, and when one person pokes, the other can poke from return. When an individual nudges another, it keeps showing up on the user's home page. As long as the person doesn't remove or poke you either, you can't poke them again.
In more recent versions of Facebook, it is possible to poke the person in the following way: go to the person's profile, click on the "gear" from the settings and the option "Poke" should appear.
The poke functionality on Facebook doesn't just have one meaning, it depends on how each person interprets the poke. Facebook co-founder Mark Zuckerberg said of the act of poking on Facebook: "When we created the poke, we thought it would be cool to have a feature without a specific purpose. Each person interprets the nudge differently, and we encourage each person to create their own meaning."
