The phrase social business may refer to a business:
- with a social objective, i.e. created and designed to address a social problem, and is a non-loss, non-dividend company.
- leveraging the impact of social networks such as Facebook, Twitter in their marketing and communication strategies
- using social technology internally (intranet, enterprise)
(definition needs cleanup for 'what is', and in particular, relevance to indieweb)
The phrase is prominently used in the description of the 2013 W3C Social Web workshop, likely intending the non-social-objective meanings above.
