I don't miss WAP as a technology but I also definitely miss WAP and WAP-like sites on mobile. So many "lite" sites have gone full JavaScript bloat and are lite only in name. It's is not difficult to add some minimal CSS for branding and just spit out static HTML.

I find the circular reasoning or bloat amusing. "We needs ads to pay for the resource usage of adding our ads!".

Fascinating that it is still in service. All of ours has been reclaimed for faster services and even 3g is starting to go away now.
