For travellers!

This is a great project https://www.couchsurfing.org/ for those, who like to travel and to discover local culture, not just like a tourist, but with a deeper inside. By couchsurfing and hosting people at your home from other countries, other cultures, - you have a great opportunity to get inside of another culture, way of thinking, religious and life views, personality and just to communicate. a great way to build up the world peace by little piece from your side. The idea is similar to Hospitality club, but by last years got more and more popular. Of course, this project is not the perfect, and surely one must be careful and definitely carefully reading profiles and references before offering a hosting or couchsurfing.
