In the developing world, people often use quite basic technology. Many of the most imaginative schemes are using what we'd count as old tech.

You can go online now and find really thoughtful, in-depth, considered, well-informed communities around virtually any issue. If it's your issue, there are now new ways of mobilising knowledge that weren't there before. There are real bodies of significant knowledge on the web that are valuable that we haven't done nearly enough with.

If you create open technology that people can use, adapt and play with, it builds capability and they teach themselves.
