I dislike the amount of time I waste on it. I mean it only gives you a short-lived hormone release. But if you look back at the past years it gives you en empty void, if you think about that you could have used that time to actually learn a skill. I did this, and started to learn card magic, and now i'm quite qood, and people always ask me where did you get the time to learn this. Just switching habits is very effective. :)
I don't do social media sites. Only Q&A sites. But I hear about them enough to make me glad I'm not on them. A friend of mine found out through "Bookface" that her grandson was in the hospital before she even got a phone call from her son or daughter-in-law. How inconsiderate is that?
I'm not on any of those sites.
I dislike the fake news. But also the popularity contest (especially Facebook)
