Nice work!

How does the initial submission to the sites work? Am I missing something or is this currently a manual process? It would be cool if it submitted on the first comment.

N.B. If you auto add all your blog posts to HN you will get silently blocked from submitting (although it will still appear to work from your point of view). You will then need to, firstly notice this, then email the mods to get unblocked.

I've hit this myself, so now I just include a simple link to:

    javascript:window.location=%22https://news.ycombinator.com/submitlink?u=%22+encodeURIComponent(document.location)+%22&t=%22+encodeURIComponent(document.title)

You can see this at the bottom of all my posts on https://unop.uk and I've seen others do something similar.
