My answer was a general answer to a general question about the two forms of Bitcoin address and was not meant to be a technical paper or exact description of how to create Bitcoin addresses (that is what the wiki is for).  

So, I started out with "Leaving out some small details:".

Thanks for filling in a few of the technical details.

BTW, even with the additional details, the description is still incomplete because you left out the checksum in the hashing description.

Anyone who wants to know all the nitty gritty details can look it up.
