Speaking as a frequent commenter and author, I suggest this is teh system working as intended. There are not letters to the editor you put in in envelope and mail away.

When HN "published" your letter to the editor, it's not printed on atoms and distributed all over town, or mailed out to subscribers.

You can post a comment, edit it, and maybe even fix something based on feedback. I suggest that without being completely slipshod, it's better to go ahead and make a comment when you have a coherent thought.

The community will help you sort out any spelling, grammar, or attribution hiccups. I think this is a good thing for everyone, reducing friction and eliminating even self-gate-keeping.

Mixing up two homophones is not a tragedy. Someone not contributing because they fear that they'll be snubbed for getting a word wron? That's a tragedy.

JM2C, &c.

if you don't want to feel like you're pandering to HN comments, you can probably hire a consultant to do the proof reading for you! =D

I cut out the middleman and just pay people to comment for me entirely. This one cost me $34, one dollar per word. But punctuation is free so it is not a bad deal.
