Saw a good video in your Facebook timeline ? Good luck finding it again after you refresh the page.
It's a pity how 'the crowd' is now dictating the direction in which technology evolves. By trying to please the users at all times, we the tech people have now created these golden cages for users - in which their identities are commodified and sold to the highest bidder.
This is not the Internet we once dreamed about and 'social media' apps like these are getting it further and further for that vision every day.
