I love HN, and keen to start following biotech trends more.<p>What biotech sites do you know of, ideally with an article/comments community similar to HN?
Once the focus shifts from how users self-identify to a subject area, a site cannot be like HN in an important sense, because HN articles rise and fall because they are interesting or promote interesting discussion, not because they are on or off topic (even though there is some of this).<p>This allows HN to be broadly attractive. To contain articles at varying levels of technical expertise, and to be reasonably friendly to new members. Having a broad range of subjects makes trolling harder - Lisp fanbois only get a crack at Scala a few times a week, so to speak.
