For those intertested OP's blog and prior submission [1][2].
> I am thinking that other people may want to have something like that, both for nostalgic reasons and for learning programming, so I thought of asking around and, if enough people like the idea, turn this into a product.
Not an admin, but this seems totally appropriate (resubmitting your blogpost would have been the more "correct" way, since HN generally prefers links over text submissions, but doesn't really matter)
If the admins feel like that, please remove the offending post(s). Or ask me to amend them.
I have made something that I think is cool and with the hope that others liked it, but if it's out of place I can only apologise.
