Have to setup port forwarding to make it available outside your network.
I tried running it off my main PC for awhile, but it’s kind of a pain and impacted my gaming sessions. Moved it onto a $400 Lenovo server I got off eBay to great effect. Used unRAID to setup a simple server for it. Lots and lots of guides out there for it with a great community. Have since upgraded beyond that server, but it was a great start.
Yep the flaw is assuming that humans would actually select for constructive comments. It’s a case where humans claim that’s what they want, but human actions do not reflect this. We’d eventually build yet another ‘algorithm that picks what immediately appeals to most users’ rather than ‘constructive’. You’d also see the algorithm splinter along ideological lines as people tend to view even constructive comments from ideologies they disagree with unfavorably
