Indeed you are right, I've just checked the submission rules <https://news.ycombinator.com/showhn.html> and they say confirm what you suggesting.

I'll change the title to remove the `Show HN`.

P.S.: I'm not the author, nor am I involved with Firecracker; however given they've just released v1.0.0, and no-one shared it, I thought it would be worth pointing at it.

Unfortunately it seems I can't change the title anymore...

I've changed it now.

About this `Show HN` tag...

I, apparently wrongly, interpret this tag as "here is an interesting open-source project that seems to have been overlooked".

Perhaps it would be nice to have a new tag so one can easily discern between "just another article" and "an open-source project".

For example my main interaction with HN is to find new and interesting tools and projects, and such a tag would be very helpful for me.

Any thoughts? How should I tag such links in the future?

One does not necessarily tag such submissions. A link to the page with the title unedited (edited iff the title is inadequate or is a clickbiat), is more than enough.

If you must tag such submissions, Tell HN seems the best suited.

Tell HN is not a good tag for such submissions, the right thing is just not trying to gussy up your submissions - a cornerstone principle of HN. Everything posted to HN is someone telling or showing something, the tags are highly specialized. If unsure, just don't use the tags.
