Clearly there are a group of elite web designers, UI and UX specialists that parade this site, who, unsurprisingly, have empty profiles. How else are we supposed to see their portfolio of exceptional work so we know what to aspire to?
This layout might look more modern than the 1998 frames we were expecting, but from a usability standpoint, it's still weak. If your average government site has a lefthand sidebar that contains all of the navigation, that in itself is better than making your user move their eyes all over the page, forcing them to click on a button to even see the rest of the options available. On top of that, they don't look like links (they don't even have a hover state), which is frustrating enough for me, but could be entirely too confusing for average users.
Additionally, that large image is useless; the "View more services" should be visible without needing to click into it.
You cannot use argumentum ad hominem to this point. If people has to shown their portfolios or other stuff to prove their skillmanship you're only wasting time and finding on the wrong place to prove your points, since those designs may not apply or be used as a good example to counterattack the main point here.
Unfortunately, the world is so complicated that we can't make an informed decision based on speech/writing alone, and verification of achievements is one of the easiest and most accurate ways to judge credibility.
