Ok get ready for some mad truth.
People need a certain amount of social interaction to feel fulfilled/satisfied. This amount varies from person to person, but the constant is that anonymous interaction doesn't count. Meaning forums or chatrooms don't count while irl socializing and chatting online with people you know well in real life do. The part of the interaction that makes you feel fulfilled is when you form connections between the persons visual appearance, your history with them and the new experience, something that doesn't happen in settings such as the forums.
