BeWelcome: a valid alternative to CouchSurfing

Now that CouchSurfing has revealed its true nature and gone Corporate (or should we say "they finally admitted that they have always been in it for the money"?) many travelers and users of Hospitality Exchange networks are looking for a valid alternative to Couch Surfing.

Number one contender would be www.bewelcome.org, a non-profit, free and open source travel and accommodation community run solely by volunteers. The number of members is still low (compared to the millions of CouchSurfing) but the community is strong and will hopefully benefit from the new members who don't necessarily like the changes that CS is going through.
