Meta-meta; almost every time that I get something to the front page some shameless plugs appear; real question, how do you do it? Do you just browse HN and happen to see it or have a notification somehow set up? I would be really interested on seeing/getting notifications related to my projects (not just for shameless plugs, I've given tips that I think are useful for someone starting something similar as I did).

Personally, I've shamelessly plugged a few FOSS projects of mine on HN (to varying degrees of success.) It happens very rarely, over the course of years, and when I randomly stumble across something interesting. Although I only read stuff on HN once or twice a day typically, I "check" HN several times a day, scanning the frontpage in seconds to see if there's anything that interests me. If it's something relevant to a project I'm working on, and people seem interested, I might plug my project.

I've thought of setting up an alert for "opportunities to post a shameless plug" but decided against it (mostly because it seems against the spirit of HN.)

reading GP's comment history (https://news.ycombinator.com/threads?id=tomaskafka) I'm not seeing any comments other than this one with the text "shameless plug" (though I didn't look back very far).

Also, to answer your question, a quick googling turned up https://www.hnwatcher.com -- dunno if it's any good though.

Oh I didn't mean by him, I mean by a different person (probably) each time.

Ahh, okay. That sounds like evidence for the "randomly happen to see" hypothesis then.
