I'm a bit worried that everyone else knows much more about data mining and data warehousing than I do, but reassured that they plan to cover the ethical issues. And to look at how limited just using digital data is. And to think about how you could use mobile technology to connect real world and digital data. It's nicely informal and messy, and there's already problems with different tags being used on Diigo and twitter #LAK12 and #LAK2012. My first question: what on earth is "transaction-level data"? Does that just mean getting out the credit card? If you'd like to join the MOOC go to http://lak12.mooc.ca/index.html where George Siemens seems to be doing a fine job.
