What does HackerNews think of remodeling?

The original wiki rewritten as a single page application

Language: JavaScript

You are 100% right. Server was pegged at 100 and the family (me) were complaining about email not working (who runs their own mail server any more). We needed to shed load. Some things went to GitHub pages (https://github.com/WardCunningham/remodeling) and the rest turned into simple content loaded by that. There were some more complexities because of SSL and old OS but it works. Things have evolved since and will continue to evolve but expect the original wiki to remain accessible in some form.
Seems like it hasn't been updated in a while. Each page has an "last updated" timestamp. The homepage says: "Last edit December 19, 2014". There's also a Github project but hasn't been updated in 2 years: https://github.com/WardCunningham/remodeling
I'm not sure what you mean by 'youngsters'--c2.com (and the associated wiki) are still maintained by Ward Cunningham, and the effort to rewrite the wiki[1] is hosted under his GitHub account and appears to have been his decision. It appears to have been motivated by a desire to "federate" the wiki, though I'm unclear on what exactly this vision entails.

I think he needs some time to improve it. More explanations here:
