Agreed! The title of the post emphasizes the satisfying outcome, but the details about the journey are equally satisfying. That compliment is a reflection of that and it's good they acknowledged it.

People working on gov.uk design system are absolutely amazing.

People often forget that there are brilliant developers who don’t need to be 10x to produce extreme value to those around them.

Bragging isn't a cultural standard around the world.

Many cultures are very adverse against any kind of such boasting and cultivate modesty. UK is one of those countries where bragging is widely considered vulgar. Happens, but it's not considered or taken as the norm or polite.

I think this article actually perfectly sums English bragging: it's polite and short, hidden between describing the due diligence that went behind reporting the bug and the numbers of other bugs they have reported and helped fix in time combined with a semi patronizing (but absolutely true and sharable) link to how to report bugs well.

If you went further east to Asia, to cultures where any kind of boasting or bragging is seen very negatively, not just vulgar, you would've found even less of it.
