TBH: they were the first two reviews we got done and that is what the designers came up with.. we wanted to soft launch and improve rather than wait for the 'perfect sample'
we've since run about 10 more (actually getting a bunch of websites to review from HN) and the reviews are getting better so we'll be replacing those samples soon...
one thing that we've seen from these reviews is that there are some great projects out there that need website help - sometimes i think people lose site of the fact that even a small startup can look as big as Apple if they have a decent website.
(also note i'm a dev not designer - we started this idea because i've needed it countless times on projects i've been working on)
