I have heard the term "don't have a life" ever since I have joined the forumz.
I find it totally wrong. Everybody has a life, no matter how much they spend on the internet. Everybody has interests, friends, hobbies, etc.
This community does not take you away form your day to day duties and responsibilities, unless you're in prison, in the middle of nowhere with closest city being 50 kilometers away (like me), or on the MIR Space Station.
That's just my opinion...
