Hi, I'm the one who created Greater Wrong. I'm intending to announce it more widely once it doesn't have so many conspicuously missing features, but it's something I'm working on in my spare time so progress is somewhat gradual. You can, however, already log in and post comments. You can use your existing LW 2.0 username/password or create a new one. Let me know if you have any problems.
Thanks very much!
If the only thing that remained of Greater Wrong was the javascript-free access to the Less(er)Wrong homepage (I mostly disabled js in my browser in the aftermath of spectre, plus js somehow makes scrolling (sic!) on LesserWrong agonisingly slow), it would be a huge value-added for me! I also like the accesskey-based shortcuts for home, featured etc.
However, it's also a much nicer and faster interface for reading the comments and even the content!
(Testing with js enabled: no noticeable slowness; the comment navigation system is neat, though I doubt whether I'd actually use it.)
Might as well go with a bang.
