Late last week, Josh Korr, a project manager at Viget, posted at length about what he sees as a fundamental flaw with the argument for progressive enhancement. In reading the post, it became clear to me that Josh really doesn’t have a good grasp on progressive enhancement or the reasons its proponents think it’s a good philosophy to follow. Despite claiming to be “an expert at spotting fuzzy rhetoric and teasing out what’s really being said”, Josh makes a lot of false assumptions and inferences. My response would not have fit in a comment, so here it is…
I’ve talked about this before: As web designers, we can’t trust the network. Sure, we have to contend with mobile data “dead zones” and dropped connections as our users move about throughout the day, but there’s a lot more to the network that’s beyond our control.
In case you missed it, yesterday Pierre Far updated Google’s Webmaster Guidelines. In his post, Pierre lays out their case for progressive enhancement:
Just like modern browsers, our rendering engine might not support all of the technologies a page uses. Make sure your web design adheres to the principles of progressive enhancement as this helps our systems (and a wider range of browsers) see usable content and basic functionality when certain web design features are not yet supported.
Earlier today, Stuart Langridge—who I worked with on WaSP’s DOM Scripting Task Force and have the utmost respect for—published a blog response to my last post. In it, he made some good points I wanted to highlight, but he also misunderstood one thing I said and managed to avoid addressing the core of my argument. As comments aren’t enabled on his site, I thought I’d respond here.
Ars Technica revealed today that Comcast is injecting self-promotional advertising into web pages delivered via it’s Wi-Fi hotspots:
A Comcast spokesman told Ars the program began months ago. One facet of it is designed to alert consumers that they are connected to Comcast's Xfinity service. Other ads remind Web surfers to download Xfinity apps, Comcast spokesman Charlie Douglas told Ars in telephone interviews.
