I'm sorry your account got rate-limited (I'm a mod here) - it's a restriction on new accounts that's based on past abuses by spammers and trolls, and is not intended to prevent authors from discussing their work here. I've marked your account legit so this won't happen again, and I'm going to restore your comment that got throttled.

This is a significant drawback in HN's system and we're intending to fix it.
