Look past the embarrassment - if this poster gets just a handful of people to register for "shipfast" service, it's well worth the time it took to build and promote this. Those people will likely buy other stuff from the OP as well.

Loads of people on HN could likely build something 'better' by some metric, but of those, how many would still have the nerve to post it in public? I'm not sure I would. Although I've got something I'm planning to post to show HN sometime soon, my default mode is telling me not to post - someone might post something negative, and I'll be embarrassed!

FWIW, the OP isn't sharing the code, and you wouldn't have needed to show your original 1999 PHP code; just share the built service with folks. That's all most folks care about - the utility/value.

That said, there's nothing (yet?) compelling about this service that I've not seen done before. But it might be new/novel to some.
