And I don't mean playing games.
What I mean is which site gives you the most enjoyment? Or type of sites?
Foe me, unquestionably, the answer is YouTube... It has saved me well over $1000 by watching how to repair things... I even fixed my dishwasher because of the info I got on YouTube. I am an avid board gamer, and watch tons of game reviews to see what I might like, and this has saved me several hundred dollars by not buying games that aren't quite what I am looking for.
I also watch a lot of old music videos and concerts. And I watch The Fantasy Footballers during and just prior to the NFL season.
