Do you not see the irony?
We are visual creatures, we judge a book by its cover (and the only time we don't do that is if we know the author or it's recommended to us) That site reminded me of Geocities (though not as bad), I'm already put off from reading it. That was my first impression. But with so many comments, I forced myself to read through it.
With a bad taste in the reader's mouth, they start off immediately with a negative impression, which could explain why a lot of negative comments.
My issue is that the author thinks half an hour is sufficient enough to make a their site look 'half-decent' or make it non-boot strap like. As a non-designer, it's not that easy. Her points are valid though, just a lil optimistic with the time.
Another easy way to make it non boot strap like is get rid of the gradient on the buttons. Go flat with a border, ala Google Style.
