Well, my excuse is that when I'm working the internet and email are my link to the world so I can't cut off completely.
I don't really do much social, other than PO, which is enough; I do look at my relatives pics on on FB a couple times a week while trying not to read anything they post or repost too closely. I read a lot online though. MSM news sites mostly, some lefty opinion, some apolitical prepper, homesteader type sites occasionally. I also use a web-based free library. I used to spend lots on books and magazines, now I spend lots on broadband.
Like Newfie said I love that I can type in the model number of whatever and know everything about it, troubleshoot it, rebuild it, buy parts, watch some guy on youtube make the mistakes so I don't have too, LOL. Ditto construction: advice, examples, codes, ideas, buying fixtures and stuff, fantastic. I shop the big box stores for commodity stuff online, and online specialty stores for just about anything you can imagine, it's great.
I like the debate on this site, usually, sometimes it gets over the top and I abstain. I like when people post more than just their knee-jerk opinion and have done some thinking and research rather than just regurgitated some winger talking point, or banal conspiracy, or More Cynical Than Thou platitude or Doom/Not Doom or Peak/Not Peak ping-pong. Some folks are so repetitive they go on ignore just because they only have one thing to say.
Posting gives me the excuse for navel gazing that I don't really have anywhere else. My wife and I talk about most everything but she doesn't usually sit there while I go read 10 sites and stare at the ceiling trying to figure out what's real or how I feel about it.
We have Amazon Prime for movies, and broadcast that we really only turn on when there is bad weather. And no cable because it pisses me off to pay for access and be forced to sit through ads too. LOL
The legitimate object of government, is to do for a community of people, whatever they need to have done, but can not do, at all, or can not, so well do, for themselves -- in their separate, and individual capacities.
