Opinions on the digital footprint?

Everyone who uses the Internet has a digital footprint, so it is not something to be worried about. However, it is wise to consider what trail of data you are leaving behind. For example, remembering your digital footprint may prevent you from sending a scathing email, since the message might remain online forever. It may also lead you to be more discerning in what you publish on social media websites. While you can often delete content from social media sites, once digital data has been uploaded and shared online, there is no guarantee you will ever be able to remove it from the Internet.
