If you turn on the "showdead" flag on your profile you will get a lot of insight into how HN works. Particularly there are a lot of people who post a link to their blog and another link to their blog and yet another link to their blog and these always start out [dead].
If, on the on the other hand you regularly post links to other people's blogs and participate in discussion you won't have any trouble slipping in a link to your own blog. The key is you're expected to be part of the community.
Also, part of the etiquette is to only post when you actually have something to add to the discussion. If you just want to say "thank you", that's what the upvote button is for.
