I'm not picking on one commenter here. Many HNers post substanceless one-liners. Please don't do that. Re-read what you've posted and, if it adds little of substance to the discussion, delete it. Fewer substanceless comments will mean a higher signal/noise ratio for all of us.
Edit: someone pointed out to me that kasey_junk is one of the few people who actually knows what they're talking about in this thread, meaning that he/she has contributed much more signal than noise. That's probably true! I don't have time to read all the threads, even the interesting ones—especially the interesting ones. I'm sure kasey_junk couldn't care less, but I've restored the karma that his/her account lost to downvotes here.
Keep in mind that HN is going through a period of experimentation while we figure out how to address some of the longstanding problems that PG never had time to take care of. We're going to get a lot of things wrong on our path to getting things right. We're also very interested in your feedback on these experiments, so don't think the feedback is one-way. The best channel for it is [email protected].
