Facebook has the most social aspect of affordance among the given ICT tools. This is because Facebook is primarily a social networking platform that allows users to connect and interact with friends, family, and other users. It provides features such as posting updates, sharing photos and videos, messaging, joining groups, and participating in events, all of which promote social interaction and engagement. Mindmeister is a mind mapping tool, Edmodo is an educational platform, and Flicker is a photo-sharing platform, none of which have as strong a focus on social interaction as Facebook.
