I didn't mention publically available. But you can bet if you ever want to work for the MoD or other gov agency, it will be used in the vetting process.That's a far leap to go from being logged to being publicly available to all though?
Even private companies will be able to make use of private detectives with inside contacts to "research" data on your habits. Replied with a "rolleyes" smiley? Clearly you're an arrogant individual and we don't want that kind of person working for us.
