Lately I try to avoid submitting my own website, per the HN guidelines discouraging promotion (the one exception is when I find a submission to be time critical). I only link to my own site in threads where it's directly and precisely relevant, such as this one.

If you found it valuable, you should submit it yourself. I'm not interested in the accumulation of updoots, feel free to get 'em. :)

I'd rather other people decide what subset of my writing is relevant to HN, as I'm no good at it: I'm too close to the work. (I only write about things I care a lot about.)
