Hi Elizabeth – I haven’t done this activity yet but it is interesting seeing your results. I do think there is a barrier for people if they have not used any of the social media tools before, as there is a learning curve with some of them. I think Twitter in particular takes a bit of time to fully get. You have to not only add lots of people but start making useful connections and engaging with them before you really see the benefit, which can take weeks or months. I often liken it to being on Facebook without any (or with very few) friends on there – you just can’t see the point at first. If you have to overcome a lot of these barriers before even starting with grappling with course content, you can see how time-consuming this would be. Having said all that – I usually advise people just to dive in and try and engage. You can learn a lot by observing how others use the tools and interact with one another.
