<p>> As a trivial counter example Git does not currently have a way to store conflicts inside commits[1], which is one of our major features.<p>Yes, I like how jj does it!<p>Did a big `git rebase -i` yesterday and I felt stressed up, almost a bit angry, when there were some conflicts and I wasn't sure if I'd resolve all of them before it was time to leave, and work more later from a different laptop.<p>But with jj, no stress: I can just check in the conflicts, and later, on the other laptop: check out the conflicts and continue resolving.<p>(I just wish there was Git submodule support :- ))</p>

<p>Yes wouldn't an 11 years old say "I don't know", or start thinking about square shaped trees?, hmm.<p>But this is the only AI that gives a good answer to:<p>> Help me teach my parents cat to fly!<p>> To teach a cat to fly, you will need a bird, a rope, and a harness. First, attach the harness to the cat and tie the rope to the bird. Then, throw the bird into the air and encourage the cat to jump after it. Once the cat has caught the bird, gently pull the rope to lift the cat off the ground. Be sure to keep the cat safe and secure during this process.</p>

<p>> no one cares about forums anymore so trying to innovate in the space is a waste of time<p>Not sure about that. To me it looks as if Facebook is self sabotaging, for example their local events page is broken and has been for years. FB-the-company seems defunct internally, and if they start fading away (slowly over many 10s of years), maybe forums will make a comeback (slowly). Also, if AIs destroy Reddit, this might be an opportunity for smaller forums that have ways to block boring AIs.<p>> Any feature you can think of has probably been implemented by someone at some point<p>Definitely not :- )</p>

<p>That's how GitHub discussion works :- ) (or did you know?)<p>Look here: <a href="https://github.com/jj-vcs/jj/discussions/" rel="nofollow">https://github.com/jj-vcs/jj/discussions/</a> — by default, sorted by last activity. But you can also sort by newest, or by votes.<p>For comment threads, look at e.g.:  <a href="https://github.com/jj-vcs/jj/discussions/5509?sort=old" rel="nofollow">https://github.com/jj-vcs/jj/discussions/5509?sort=old</a> — sorted by time, by default. But you can also sort by upvotes.<p>***<p>The forum software I'm developing, <a href="https://www.Talkyard.io" rel="nofollow">https://www.Talkyard.io</a>, is also threaded, and can sort by time or by votes. (Both discussion topics and replies.)<p>F.ex. go here: <a href="https://forum.talkyard.io/-9qb49/solving-problem-first-comment-gets-all-upvotes" rel="nofollow">https://forum.talkyard.io/-9qb49/solving-problem-first-comme...</a> and scroll down to the replies section and click `Oldest first` to change order.<p>In addition to oldest/newest/"best", you can sort top level comments by time descending, and deeper comments by time _ascending_ or by votes — creating a kind of "micro blog feed" where each top level comment is the most recent "micro blog post" — but replies don't have to share the same sort order.  "Newest, then popular" and "Newest, then oldest" I call these sort orders.<p>Also click the "Recent posts" in the upper right corner, to see the most recent comments sorted by time descending.<p>***<p>Anyway. There's people who think the hybrid approach you mentioned is an good idea.</p>

<p>Interesting, didn't know about that Github functionality.<p>I'd like to not depend that much on Github, and instead I'm thinking about having some kind of archival repo where noisy boring historical stuff can be saved (but I'd delete the branches in the main repo). Or renaming historical branches, eg adding an "old/" prefix.</p>
