When I quit I ended up reading books and watching TV for entertainment. I literally read over a million words of fiction (Worm) in one month with the spare time.
It was a lot more fulfilling, and I'll remember that time. While in contrast there are few social media moments I'll miss.
I had to actually force myself to get back into social media. I'm not sure what the author here means by withdrawal; there was maybe a period of 1 week trying to get back in, but it was over quickly.
One big thing that happened was the number of consulting contracts went down significantly and never recovered. I'm quite Facebook active and used to get two interview offers a month. In fact last month I got a huge opportunity that I would have gladly accepted if I wasn't committed to anything else.
I'd be happy if social media was just wiped out and we went back to socializing on forums and IRC.
