Forget nosy neighbours, it's the cyber world that none of us can hide from now
One of the many problems with social media is the 'you can never take it back' aspect. What teenagers and indeed adults need to remember is, once you've posted something it is not possible to take it back.
Sure, you can go in and delete it, but by then it will have been seen by lots of people and quite possibly tagged or re-tweeted. The problem with teenagers is that they rarely stop to think, and more often than not, say exactly what's on their mind, unaware of the potential repercussions.
Social networking sites are not all evil, they have a positive side in that they help people across the world to keep in touch with friends and family and to create new friendships.
