Why not post the whole content? You post the whole content on other sites, why not on FR?
Because of bandwidth. I admit I get a little exuberant or giggly at times and will post a response in 36 pt or so font. And sometimes I’ll write an overlong response. But it costs JR bandwidth, so it is a good thing to excerpt the article on FR. I haven’t been able to contribute to FR for the past two years because of an illness in our family, so I remain conscious of costs.
