Search all of these Open Education Sites from one place. Got a new site? Log in as username: edtechpost_guest (same password) and add it to the list. Simple, eh?
piwik is an open source (GPL license) web analytics software. It gives interesting reports on your website visitors, your popular pages, the search engines keywords they used, the language they speak… and so much more.
"The model is free. You can use our content elsewhere in the web. What do we get out of it? We want you to help us build an ad network," said Matt McAlister, head of the Guardian Developer Network.
To find related Guardian articles, the API can draw on the tagging system from its own content management system, internal search engine for guardian.co.uk provided by Endeca and a related-content service powered by Zemanta. That content is then packaged in standardised formats including XML, JSON and Atom which can easily be added to external sites.
"The whole idea is to spread out journalism," McAlister said, and APIs can lead to explosive growth.
Twitter's API drives 20 times more traffic to the service than its own website does, and Twitter's web market share passed that of social news site Digg in January. Third parties using Twitter's API have developed a huge range of services and applications that have helped drive Twitter's growth spurt.
