The Younger McGarr (Simon that is) has a very detailed and well written post on the data protection issues that arise (and seemingly are ignored) by Facebook. It can be found over at the McGarr Solicitors website. He has already picked up some complimentary comments, including one from Thomas Otter (who has written on these issues previously). (Surely a reply from Robert Scoble is only a mouse-click away?)
I’ve been scratching away on some notes for a post on Facebook myself (never one to miss a rolling bandwagon me). Expect more on this soon. (ie as soon as I’ve written the buggering thing).
