Opting into Experimental LW Features

We re­cently added an “beta test­ing” op­tion for LessWrong. If you go to your ac­count page, you’ll see a check­box for “Opt into ex­per­i­men­tal fea­tures”.

Right now, the pri­mary fea­ture un­der de­vel­op­ment that isn’t yet re­leased to the pub­lic is Sin­gle Line Com­ments. This is an at­tempt to fit more over­all com­ments in some ar­eas.

Re­cent Discussion

For ex­am­ple, re­cent dis­cus­sion now looks like this, where each post loads 4 com­ments (and high­lights them if you haven’t read them), but only shows sig­nifi­cant amounts of text from the most re­cent com­ment:

You can click on a re­cent dis­cus­sion item to mark that item as ‘read’, and make the green line go away.

Posts with 50+ Comments

On posts with 50 or more com­ments, com­ments be­low 10 karma will ap­pear as a sin­gle-line com­ment:

Mous­ing over a Sin­gleLineCom­ment will show a hov­er­card with a pre­view of the com­ment.

Click­ing on a thread will fully ex­pand all of the chil­dren of the com­ment that you clicked on. Do­ing a search (Con­trol+F, or Com­mand+F) will also ex­pand all com­ments (so that you won’t run into an­noy­ing things where you try to search but the com­ment isn’t dis­play­ing all the text so you can’t find the quote you’re look­ing for.

This is all still un­der de­vel­oped. Ad­mins of the site have been us­ing it for the past month or two to see how it works, and tweak­ing it un­til it felt us­able. It’s now at a point where it seemed good to let other LW users try it out and see if it seems like an im­prove­ment.

(Be­fore re­leas­ing it pub­li­cly, we plan to build some sort of safety-valve-check­box where you can turn it off eas­ily)
