It wasn't that long ago we were told not to give out any info about ourselves on the evil interwebs. Prime examples were of underaged girls/boys on chatting-sites/software getting tricked to meet up alone with some creep in a dark allyway/the woods. Nowadays on the other hand you have social medias like facebook and twitter on the nets where people share whatever they want about their personal lives. Your grandma has probably poked you numerous times on fb, it's mainstream, for everyone. What are your thoughts on this social evolution? Pro's? Con's?
