Martin Dittus, @dekstop, martind on IRC. I’m a researcher in computer science at the ICRI Cities at University College London. I am currently researching community engagement for HOT and Missing Maps. At its core this is quantitative work, and my main outputs are statistics and data visualisations. I make use of the “hard” evidence of contributor data traces, but also the “soft” evidence of knowing the practices and motivations of the community.
