rojash I look upon FB as something I choose to use in a very limited way as it enables me to keep in touch with family abroad on a day to day basis. As ummmmm quite rightly pointed out, it's free as the advertisers want people on the site and, having given it some thought, I agree with ummmm that from their (the advertisers) pov it's there to suit them and not me but I play the game by glancing at the ads. I was just curious as to how and why certain threads from AB appeared on my FB page. Threads which I hadn't even subscribed to.
