Esperanto gives you international contacts immediately. You can skype, tweet, write or email with people of almost any country. There is even a worldwide network of free accommodation for Esperanto speakers in almost 100 countries.
This not only saves you money but allows you to visit places that most tourists don’t get to see.
Many international meetings that use Esperanto are held throughout the year around the world.
Esperanto also has a large body of international literature, with original and translated works, plus music of different styles and a rich variety of blogs, websites and publications.
