Not too mention facebook completely changes in design and is constantly evolving its look. If FB still looked like how it did in it&#x27;s early inception I doubt it would be as popular.<p>Perhaps there is some study to be done where social sites&#x2F;apps become obsolete if they fail to adapt their UI&#x2F;UX over the years. I mean look at sites like Fark and SA compared to what is popular nowadays like Snapchat or Reddit.
