this is quite cool, and it's good to see that github parks its own typos - I've seen far too many "What you need when you need it" landing pages from getting a letter wrong while typing a domain.
github.com shows that it's registered through GoDaddy. hitgub.com is registered via namecheap, and has its contacts hidden.
Then they woke up and realized what a STEAMING PILE GoDaddy is as a company, and corrected the error of their ways for their other domains. :)
Just my random $.02 :)
