I’ve used MSN Messenger for years now, but have developed the bad habit of setting myself to ‘appear offline’. In theory that means I get to choose when I talk to people, but in practice I just never look and I end up talking to nobody, which is silly. So from now on I’m going to set appropriate status messages in Skype, MSN, etc. If I’m around and not too busy, I’ll be simply marked as ‘online’, otherwise ‘away’, or ‘busy’, or whatever. It’ll probably take me a while to get used to it, however, so please don’t be offended if I don’t reply!
