Anecdata:<p>I don&#x27;t use FB, but it turns out that people can form pretty strong bonds over incidental things. At least those bonds appear to be strong to the people on the outside, and that&#x27;s all that really matters when you&#x27;re talking about social stuff.<p>At this point in my life, the costs are negligible, but ten years ago those same cost would have been closer to &#x27;devestaating&#x27;.
