This was our favourite way for us as students who were unable to take part in our university's annual competition due to time constraints (the deadline being one day before) could still get involved by using social media! It made interacting with other participants much easier than if we had done things independently or via text messages which are not always easy when far away from home / city centre etc. I would prefer there be more options available so people don't feel limited - but overall its been great! We have used it at events such as student fairs where many different groups attend together including disabled people, those living alone etc; allowing them to connect easily.
