What's your opinion about #couchsurfing and #flatsharing, and it's plattforms?
(I'm talking about sharing not rbnb or similiar ;-)

What is your experience?

When it comes to travellers' networks, there are some:
Hospitality Club
Trustroots
BeWelcome (based on free software)
...

They are less used than CouchSurfing, but nice. I have little experience on them (HC and BW), but it was good. People there have a more alternative approach. The atmosphere on CouchSurfing is changing to a very commercial/dating spirit.
