“…These important characteristics include knowledge sharing is voluntary [45], support for social networks, user-generated content, enforcing much less sense of hierarchy than in the real world so anyone can provide feedback or comments to anyone else and one person can be at the same time part of several networks [40] [46] [47], and establishing of weak ties, which refer to acquaintances with less social involvement, more superficial and on a smaller, less intimate basis [48].
