Web 2.0: opportunities
Painting: Orion aveugle cherchant le soleil, Nicolas Poussin
- powerful services available to many more
- standing on the shoulders of giants
- a great pool for innovative ideas with a lower threshold to entry
- finding value from social interactions
Offices suite, learning from videos, sharing of knowledge and information on blog
can build great services based on the API made available by others: e.g. Google Maps
social networks expose new form and set of data
Web 2.0: challenges
- limits of ad-based business models
- centralization of data and infrastructure
- privacy and control of digital assets
Web 2.0: challenges specific to developing countries
advertizing needs a market
start-ups needs fund, but only few opportunities for funding in developing economies
market to sell ICT-based services much smaller due to infrastructure limitations
network deployment (mobile help)
reliance on heavy Javascript usage => greater need for hardware ; mobile Web deplyment helps somewhat; also, "graceful degradation"/"progressive enhancement" helps
un-localized content and services make them less or not useful in many countries (but an opportunity for local development of local equivalents)
Sanaga: sharing of videos and music
MamaMikes: sending voucher gifts and more to Kenya
(quite a few have already closed: Amagama, grabble, ...)
Web 2.0 for developing economies
- Brosdi: sharing of knowledge in rural Uganda
- WikiForets for the preservation of central Africa forests
