Facebook (it's how my relatives choose to communicate), Cloudy Nights, EBay, World of Tanks, Family Handyman. It all depends on what I'm feeling at the moment.
Back in my astronomy days I spent much time on cloudynights ! Havenβt thought of that site in a long while !!
Facebook, Grepolis, some dating sites. I don't spend a lot of time online. I have a very active social life.
Mostly Quora. I do short and somewhat rubbish answers on there, and make scathing comments on answers I think are stupid. Other than that, I like watching various genres of video on YouTube.
I love the atheist rebuttal sites on YouTube. They are a great place to learn. My home is athiestnexus.com but it seems to be dying. I often answer questions concerning Christianity on quora. This is now my go to site.
