What is a good online chat service that is not old, lame, petty, or about hookups?

I work a night shift and also up at night so get bored. All of the chat services seem either older (IRC), lame, or all hookups. I have tried Stickam and other places. Is there anywhere to just have a conversation about current events, the weather, life? I think sometimes all the chatters have been taken by online gaming or hookup sites depending on their interests.
