Helping each other, exchanging services with neighbors, has always existed.
Today, with the Internet, mutual aid networks are developing in neighborhoods to offer various local services (large or small DIY, babysitting, cleaning, walking or pet-sitting, moving, lending objects: e.g. tools, kitchen appliances, etc.)
What do you think of this exchange system? Would you be willing to ask or provide a service to strangers living in your neighborhood via the Internet?
