Usability 
The blog of FAILFaire, a conference focused on learning from failed ICT4D projects.
ICT4D is an acronym for "information and communication technologies for development" which means using technology, especially computers, web and mobile, to enable and encourage socioeconomic growth and human rights. Examples include the One Laptop per Child Project and MedAfrica, which lets rural users connect to doctors and medical information using basic mobile phones.
Not all projects are successes. FAILFaire aims to help ICT4D professionals and participants learn how to succeed by understanding what doesn't work.
