V&RVisitors and Residents (or V&R) is a really useful way of thinking about how people interact online and use social media. In short, people in Visitor mode come online to complete a particular task, and then leave - with very little trace of their activity remaining. People in Residents mode are more likely to identify as themselves and use the web as a social space, sharing as well as obtaining information.
Visitors and Residents is a continuum which all of us are on, moving between the two according to our needs at any given time. It was first proposed by Le Cornu and White, and (David) White has a very useful section of his site to introduce the topic in more detail.
As libraries, it's really useful to think about how we go about catering for users in both modes. Social media isn't all about social networks - we can use social media platforms to provide easy entry points for Visitors seeking information (a lot of the platforms I've set up at York should provide utility even for students and staff who don't use social media at all), AND we can use it to add our voice to a more Residential space and provide help and information as part of a community. Led very much by Donna Lanclos's views on the subject, I now see V&R as a far more constructive lens through which to view peoples' online behaviour than the 'Digital Natives' idea, which is extremely prevalent and asks us to make assumptions about our users based on their date of birth.
I was invited to give a keynote at the Interlend conference, and asked specifically to talk about social media. As I've mentioned before I think a keynote is a very specific thing, and has different requirements to a regular conference presentation where I could, for example, just report back on what my institution is doing to engage users online. A keynote needs an overarching theme which gives people a way of looking at the world, as well as specific ideas and things for people to try out. With this in mind, my #Interlend2015 talk was entitled Visitors and Residents: Useful Social Media in Libraries.
