It may be the place for short and punchy posts, but they should still follow the style and voice of the rest of your content. It’s unlikely that educational establishments are going to find comfort in the sort of comic feeds that the likes of the US food chain Wendy’s produces.
Social posts should be informative and helpful, still promoting that coordinated brand voice. Twitter, for example, is a great place to post or find relevant educational news, whilst LinkedIn is much more likely to connect you with academics themselves or even potential sponsors. For this reason, you should consider your messaging on each platform rather than ‘social media’ as a whole.
