I have moved all my QGIS tutorials to a new website. Tutorials are upgraded for QGIS 2.0 and are organized by topics. Completely free and optimized for classroom use.
I am the author and the current maintainer of the Google Maps Engine Connector for QGIS.
I maintain a couple of directory websites. These were born out me just collecting information about the geospatial industry in India and eventually turned into a wiki. Now these are hosted on Google Sites and I get frequent submissions on most topics.
