I first got off FB a few years back. It used to be a great tool to keep in touch with people all over the world. When I started to see the politicization, I thought "great, this is valuable to see the perspectives of people from a different political leaning"...I think that was worthwhile, but it quickly devolved into dozens of posts showing two ex-coworkers rant posting memes at each other intertwined with updates on various ex's and ads for hoodies with my last name printed on them. As fast as I could unfriend the ex-coworkers, they were replaced by angrier ones!
As my Mom has developed health issues, I've gotten back on as a convenient way to keep tabs on all the family stuff back home, then gotten frustrated and suspended my account. That cycle's gone a few times, with the 3rd account suspension being about 3 months in right now.
