Giving for free, whilst the Security Agencies have to dig for it
And theres the lesson of the story.
Our interpid Scot is happily helping the Mobile network, and Twitter build a handy little database about who Her friends are and where they're located, and what data they like to share. Even paying the network for the priviledge, and sucking up the adverts on Twitter as she does so.
Meanwhile, the security agencies have to do it behind closed doors and 'in secret'.
Just remember folks...You're the product, not the customer.
