I have said a few times that LJ does seem to stimulate longer, deeper conversation but then ten years ago about half the posts were those quizzes and memes, 'which DC superhero are you', etc. That, too, has gone to Facebook and I don't miss it.
ION, an interesting article here by sashagoblin about the many obstacles and intolerances that bi people face. I'm not one myself, but wearing the tags of a few minorities and having to put up, in a much .. lesser, more minor way, with stereotypes and prior assumptions, made me think. We make sense of the world, amongst other ways, by putting labels on things and putting them in boxes, but those boxes seldom describe the whole reality of what we're dealing with -and we get it wrong. And we still deal with difference in ways that may have been advantageous ten thousand years ago but not in the society in which we live. There is such thing as progress, attitudes to these things have changed so much in my lifetime, but it is so slow and so localised.
