only on HN can I politely thank a fellow user, and for that social crime my comment is downvoted to oblivion, draining my karma. this site is unbelievably nasty at times. HN mods/devteam: I vote please remove the downvote control for ordinary users, site-wide. its the simplest way to fix this old long-standing problem. simple, shotgun solution.
