If you got a job offer that was riddled with spelling mistakes and had the wrong name, would that inspire confidence in your future place of work? It's not a huge stretch of the imagination that small, obvious issues could mean larger, more complex issues lurking.

I'd say "riddled with spelling mistakes" is a bit strong in our example (I realise you weren't claiming that about the site).

I got it out early to get some feedback. The 404 spec link is a bad one (since fixed) but the typo in the DNS record is forgivable I think – very impressed anyone spotted that.

To be clear, my comment was directly addressing my parent's comment of

> How do syntax errors dissuade you from the proposal? Is not design separate from implementation?

I would not characterize your content as "riddled with spelling mistakes" and apologize if you read if that way.
