Is it bad form to post your own stuff to Hacker News?

Every single blog post? Probably not.

A blog post you really spent some time on, that's on topic and you'd like to show off? Feel free.

I think Hacker News is generally pretty accepting of folks who submit things to HN to discuss, rather than to self-promote. If you're submitting one of your blog posts every day or multiple times a day though, you're probably doing it wrong. At least, that's how I feel. I originally came here from reddit (and started Report the Spammers there) so I'm likely less tolerant of self-promotion than some people are.

I find it curious why someone would ask this on Quora, rather than simply asking it here on HN. You would get a far more focused and realistic response - from the community itself.

I do, but sparingly, and only when I really think it might be of interest. Mostly I post stuff from others. I didn't come here to self-promote, but I am interested in the Show HN things.

I'm fine with Ask HN/Show HN.

I thought that was the idea. It makes for nice 'HN-exclusives' from out own community, which acts as a differentiator from other blog/news aggregation sites. If it's of the quality of article generally found on HN, then what's the worst that can happen - people either vote for it or they don't.

Out of curiosity: http://www.quora.com/Jinghao-Yan -- what is your HN handle? I would have expected the response to give some indication that he (im guessing gender based on picture) actually used the site ...

I believe it's fine.

As long as you're not dishonest about it.

(That doesn't require one to admit to it, but trying to actively hide one's association I personally find insulting).
