Talk presented at Cross-Currents workhop on "Rural Cultural Practice and the Digital Economy in India and the UK", at IIIT Bangalore, 12th May 2014. http://alandix.com/academic/papers/CrossCurrents-technology-at-the-edge-2014/ The talk was based partly on my 1000 walk around Wales in 2013, and partly on community projects on the Isle of Tiree including Tiree Tech Wave. I discussed the inter-related issues of being at the physical, social and economic edge, including language, identity & community, connectivity & communications, and digital heritage.
