The most recent edition of Participatory Learning and Action journal has been posted online and all articles are available for free. The theme is - Change at hand: Web 2.0 for development. Here's a summary:
Web 2.0 tools and approaches are radically changing the ways we create, share, collaborate and publish digital information through the Internet. Participatory Web 2.0 for development – or Web2forDev for short – is a way of employing web services to intentionally improve information-sharing and online collaboration for development. Web 2.0 presents us with new opportunities for change – as well as challenges – that we need to better understand and grasp. This special issue shares learning and reflections from practice and considers the ways forward for using Web 2.0 for development.
The articles cover various tools from video-blogging to twitter and have been written specifically with practitioners in mind. Ushahidi is featured as a tool for crowdsourcing crisis information.
