Further to "Feed my delicious mind"...
A workshop I ran a while back entitled: 'An Introduction to Online Collaboration Platforms'.
To my knowledge, this is the first and only computer workshop hosted by the Durham University Engineering Society (note: I would love to run a workshop on ardunio after exams...if you want to get involved then get in touch): http://docs.google.com/Present?docid=dg4dhwgp_12fpkcbv4j
It is a quick presentation with some links to youtube commoncraft videos and some urls with examples of the platforms in use. Click, watch, install delicious and then please share bookmarks with me! username: samthetechie
