The Facebook marketplace is, I hear, a great place to buy shit you don't need but also for construction businesses that are small it is great for them to get trucks, trailers and equipment from similar business people. I imagine other small professionals benefit as well.
We have to be honest in our criticism.
Since I'm not buying or selling that stuff the Facebook, LinkedIn, Twitter, Instagram and other experiences I wasted time on for hearts, likes and arguments or sycophant agreements is not worth it.
