For me and my fiancee it was Reddit. We'd spend hours each day on there just meandering away the day, and not even realizing it. I blocked Reddit on our network at home about 6 months ago and we haven't logged in since. We're both much happier people now. I think Facebook and texting need to come next.
We've talked about this several times and came to a pretty surprising conclusion: in today's world television is actually pretty "healthy". It involves truly turning off the brain and actually relaxing and escaping, and requires an attention span of 22 minutes or more. With Reddit, Facebook, texts, etc, you constantly shift attention every 20 seconds, and never really allow your brain to turn off and disengage. You're neither relaxing nor being productive; at least tv has a level of relaxation to it. Kind of frightening.
