Over on Pingoat, he is having problems with Technorati not indexing them or any of the pings [http://www.pingoat.com/goatlog/post/index/26/Technorati-problem]. I had this problem a while back and I am still getting it over on www.tagger.com. I think it might stem from if they try to spider your site and some part of it is not responsive then they take you out of their list of "blogs which work". I am not too sure how to get it back in, unless you constantly complain in high profile places! Their response to emails is notoriously slow/non-existant.
I lead the Chrome Developer Relations team at Google.
We want people to have the best experience possible on the web without having to install a native app or produce content in a walled garden.
Our team tries to make it easier for developers to build on the web by supporting every Chrome release, creating great content to support developers on web.dev, contributing to MDN, helping to improve browser compatibility, and some of the best developer tools like Lighthouse, Workbox, Squoosh to name just a few.
