Ideal for organisations
If you are looking for a domain extension for your organisation, .org is probably your best option.
Trust is ensured
Convey trust and integrity to its users with the domain extension .org.
Despite not having minimum requirements for its use, the domain extension .org is normally associated with social areas. If your project is of that nature, start positioning it with your domain extension.
Address a wider audience
As it is not a domain directed at a specific segment, you can use it like other generic domains to address the general public.
