Unsure whom you're apologizing to, but none necessary. Even our little internet refuge here is still a social media site, and social media generally is horrible and frustrating at times. I delete my Twitter app often, only to go back eventually. I think taking a break is healthy at times. I took a several month hiatus from most of the internet after the election, and I'd say it was generally good for my well being. Hubski has the unique feature of changing your username to "user-inactivated" (which I don't care for--we all should have to be responsible for what we put into the world), so it looks like a protest rather than a hiatus. I'd encourage everyone to take a break from time to time, but maybe don't inactivate your account. Just log out. It's that simple and also that hard.
