I couldn't agree with Matthew on this topic more.

Having a personal website is something most people my age don’t do. However, most millennials have a web presence via social networks like Instagram, Facebook and Twitter. Having a web presence is very important, and is almost a requirement in this digital world. Using social media for your web presence works wonderfully, but you don’t own and control your content. At any time your social media account could be deleted, and then your long time web presence is gone.
