It was probably 'enjoyable'. That was one fault that didn't stop me reading on. While we're at it though, 'Checkout' used incorrectly did stop me, however, because in the software context 'checkout' could refer to more than just supermarkets. I'd fix that one. Especially on a call to action. I'd also fix 'fine file'.

Scoring grammar points could be seen as nitpicking, but I think in a Show HN situation, where fair criticism is welcome, it's helping to improve presentation and conversion rates. If some kind of 'foreign bias' kicks in for some visitors you might lose the conversion completely. Copy counts. In any language.
