I'd just assume that they needed to create an account to comment and picked the first username that came to mind. Quite logically, this was a couple of words from the reply that they had already formulated in their mind.

Maybe it's the start of a reddit like novelty account. There sure are a lot of "not exactly" situations on HN. Could make a karma mint on any patent thread.

Wow, now I wish I'd thought of having a notexactly account.

Maybe I'll have to settle for yesbut

You may have this one (if you can live with a throwaway). I have posted my original account in a comment above. It has my email ID in it. Email me and I will give you the password. Before that I will make a comment here stating that I have transfered the account and will wait till the delete option is gone. Seems fair?

Is it still called a "mint" if it's all downvotes?
