OP this just links to your home timeline on Twitter. Don't submit tweets (unless the tweet is the only source of information and tweeter has a reputation in their field), submit the link contained in the tweet you got excited by. Delete this and try again.
Sorry about that. Shenanigans it seems. Not sure what happened. This is the correct link, but will try to resubmit:
For some reason whenever I submit the correct Twitter link from the team (which adds some nice color to the paper), HN seems to automatically modify the link to just point to Twitter-home post-submission.
