As an example, I can't tell you a thing about competitive professional sports or
current sitcoms. I don't watch TV...What I spend most of my spare time doing is being online.
I suspect that this is a red herring. You waste a lot of time on IRC.
If you stopped doing IRC you would watch TV and get just as much done.
(This isn't a suggestion, of course.)
I don't think anyone can be 'productive' all the time.
But some people watch TV in their downtime and
other people watch IRC; I don't think it's really that different.
