Hi Kristine,
Your right - maintaining/updating marketing collateral becomes more difficult to manage when you are using digital media that is published online. This is why I teach students that they don't have to use every social tool out there but to choose the ones they can/will manage and keep current for career marketing purposes. There are automation tools to help maintain a presence and stay relevant. Tools such as Bufferapp, Hootsuite, and other social media management tools make managing one's social accounts easier. I also point out to students that while it may be more difficult to maintain, the truth is one should always be maintaining/updating their marketing collateral so this challenge can also act as a motivator to actually do it. Additionally, doing so helps develop and demonstrate valuable skill sets such as technical literacy, social media management, marketing and communications, all of which can enhance one's brand.
