Interesting move by Facebook to team up with retailers and share information: automatically updating your Facebook profile with purchases you have made. I can see why people don’t like it – I choose what to post on my blog: it isn’t done for me. Without this control, I don’t know if I necessarily want to publicise my SlingBox (or equivalent)? And just imagine how many presents this could mess up: “I see you’ve bought X. Is that for me?”. Or maybe this is a previously-unseen Christian-right agenda to lessen adultery?
