Matt, neither my code nor design will ever match someone who specializes in these areas. So I feel you're kind of missing the point. I never claimed to be a great anything so I wouldn't go jumping to conclusions. I simply do a little of everything. Kudos to your HN detective skills, Cookbuk was a weekend project hacked together playing with CI. Full blast reviews of missing or nested DIVs are a waste of your time that could be better spent on your startup. If you're looking for UI help on your corp or other products (which could use a refresher), lets chat.
You did say you had killer UI skills. Checking someone's comments and profile takes like 10 seconds.
I pretty much check the source HTML of every startup or demo site I see on HN as a matter of professional advancement and to see what they're using. People sometimes put easter eggs in their HTML or headers too, so it's fun too! Or even better when they're not minifying their JS and leave stupid comments in.
You'd be surprised about how much someone's HTML can tell you about them.
