It doesn't, that's just your fan club talking. It looks like a run-of-the-mill WordPress theme.
What you just said translates into "Design doesn't really matter." There is a difference between doing minimum needed not to scare away customers, and refining the design to appeal to both existing and future audiences. Latter is the case of why design matters, former is not. Former is just the same common business sense that dictates to not be rude to your customers or not use green on red text.

That gives me an idea: What if HN hide usernames until you'd voted on a comment (or hide it for X minutes). That'd be an interesting technological change.
You've managed, in the most irritating possible way, to tell us that you find Patrick's blog template bland. Does anyone find this helpful?

A usable site that is a bit ugly will win over a great looking one that confuses the user. Craigslist is the best example of this, it doesn't look great, but millions of people use it. Foursquare wasn't as pretty as Gowalla, but it won because it was a better game - becoming mayor was more engaging than dropping teddy bears.
BCC was well designed in that it delivered exactly what people were looking for. Sure, it may convert better if it looked better, but it was successful nonetheless. But the whole point is that Patrick has learned that visual design also matters, which is why appointment reminder looks better.
