it's nice to have friends online but tu have to be careful with friends online since tu don't know them. tu also need to make sure tu have friends in real life too but as long as they make tu happy it's nice to have all types of friends.
Nah, I don't think so. Your online friends are real people, too. I'm sure they appreciate having someone to talk to at the end of the day. It's easier (for me) to talk to my online friends than the people I know face-to-face. Any friendship is special. No friendship should make anyone look bad.
