Oh I didn't mean to criticise anything you're doing. There's no such thing as bad data mining, only bad analysis of the results :) I just worry that people in our governments and security services will sieze on work like this which is largely being carried out for the amusement and satisfaction of academics and general geeks, and decide that it is appropriate to make specific judgements about specific people based on the data. It doesn't help that I read this article just after I woke up this morning: http://www.guardian.co.uk/uk/2011/may/03/protester-sue-police-secret-surveillance http://www.guardian.co.uk/uk/2011/may/03/protester-sue-polic...
