I have an aging Sony TV that refuses to die, and the cheapest possible cable package. Some days I watch nothing. I scan the TV listings to see if there's anything interesting, and then more often than not forget about it. Other days I'll watch an hour or of something in the evening. A local channel carries local news 24/7 so I'll often check on that for a quick update. On the odd occasion, the local PBS station carries something I make a point of watching.
My RFF time varies significantly. Sometimes I'm here a lot, sometimes not. It's a great resource for answering questions and satisfying curiosity. When I'm thinking about trying something new, or when I've run up against a problem, or even in the throes of a GAS panic, wiser, more experienced people will invariably have posted something useful here. In particular, comments about cameras, film, etc. are more useful and more accurate than articles on dedicated review sites.
TV and general web use, including RFF, do suck up time I might be spending working my way through my overly large stack of Books-To-Be-Read.
