Not sure how that happened. And I can't resubmit the URL either
The mods can (and will) fix it. You can also email hn@ycombinator.com and let them know about this error.
Thanks. Sent out an email.
That was indeed a bug at our end, in the code that attempts to write AMP links. Sorry! I've pushed an interim fix, so you should be able to resubmit it now.
It is a nice resource, but the number of spelling and grammatical errors is ridiculous and becomes very distracting. Please use Microsoft Word or some other spell checker on each page.
