I miss the days when web developers still gave a shit about progressive enhancement.
I miss the days when you couldn't be considered a real web developer unless you could make a CSS Zen Garden (http://www.csszengarden.com) skin without cheating by changing the markup or using JS.
I miss the days when you were only considered a good web web developer if your site was usable with both JS and CSS disabled because you used semantic HTML.
I miss the days when accessibility still mattered.
I miss the days when writing semantic HTML, enhancing it with CSS, and enhancing it further with JS was considered the best practice, rather than starting with just JS and an empty body tag as is so common today.
I miss the days before the now popular false dichotomy of thinking that progressive enhancement is extra work was popular among web developers.
I love that the web can do more now and compete with native apps better. But I hate that web developers are so quick to unnecessarily abandon progressive enhancement in the process when that's what made the web great to begin with.
