I agree -- I'd rather come back every ~6 months with big updates rather than have the link submitted constantly. I'm always planning to submit it myself when I reach a big milestone but someone always beats me to it... it gets a fair amount of organic traffic and Github switching to the .io domain for pages probably made it fall through the cracks of the HN submission map.

That being said, I think I'll resubmit when I get the origin lessons in place (WIP here:) http://pcottle.github.io/learnGitBranching/?NODEMO&command=g...

And then hopefully I'll be out of everyone's hair forever.
