Social Media - where are we going?

I hate social media and I hate it even more now that I am told to use it for work! Just joking... this is the biggest thing since sliced bread - what will be doing in 10 years time - feeling obliged to tell everybody what you are doing every 10 seconds of the day - who is really interested in personal blogs? We can learn so much about people's private lives but what happens when this information is used in the wrong way - do we really want people to know everything that we do?
