Describe How Facebook Leveraged Crowdsourcing to Rapidly Expand Internationally, All

Describe how Facebook leveraged crowdsourcing to rapidly expand internationally, all while minimizing staff needs.
Facebook leveraged crowdsourcing to develop versions of its site localized in various languages. Facebook engineers designated each of the site's English words or phrases as a separate translatable object. Members were then invited to translate the English into other languages, and rated the translations to determine which was best. Using this form of crowdsourcing, hundreds of volunteers cranked out Spanish Facebook in about a month. It took two weeks for two thousand German speakers to draft Deutsch Facebook. All were done with a minimum of staffing, as opposed to the high cost the firm would have incurred if it had hired native language experts and enlisted focus groups to verify its translations.
