The old idea that everyone on the internet is a creepo who will rape, kill and pillage is very silly. There ARE bad people like that on the internet, and there are at schools, businesses, walking around in the general public. However, there is just as many amazing people who aren't dangerous who may be too shy to approach groups of people like this under normal circumstances. This gives them that chance, and helps show people that their outdated view on internet uses is incorrect. :)
