Your profile reads ~"inescapable idealism" yet you sound like the most jaded person I've come across lately. Downvoting isn't the problem, it's probably cynicism. Nailed it.
An idealist can be positive about a state of affairs and the future. He need not be disappointed that utopia has not yet been reached. I find HN encouraging, because the tone and contents are mostly pretty good. So where does your disappointment come from?
