The other way to look at it - 97% didn't react to your shameless plug, and probably a good chunk of these were annoyed by it. An ad is an ad, regardless of how you call it.
I think that's a pretty bold claim. I can't remember ever being annoyed by a blog post which included a brief "This is me and what I do" plug.
Right now we have on or just falling off the front page
- 37signals writing about Siri
- Thumbtack writing about ab testing
- weddinglovely on why a startup has a print product
These are advertisements disguised as random bla bla written for HN.
There are a few authors I wish they advertise themselves more on HN.
In this order of ideas related shameless plugs are better than most other forms of advertising.
