This is one thing I like about HN's system: it lets me edit posts for a limited period. I'll sometimes bang out a post like the above, with a rather negative opening line like that and hit "submit". Then a minute later I'll realize I need to tone that down some, so I'll go edit it, as you suggest here. Unfortunately some shitty web forums don't allow you to edit posts at all, but I do appreciate ones which do allow editing stuff like this before anyone has a chance to read it.
