he mentioned regional forums, so I assume a large part of what is missing is a common culture/language instead of whatever conglomeration comes out of the US.
the EU regulations made it harder/less attractive to host a small local forum and I think that was his point
In many countries internet forums are technically banned by regulations.
HN posted that many user forums in UK were simply deleted because of the excessively heavy burden of the law.
I would love to go back to people not using their real name and an internet that is wild, free and maybe even a little bit dangerous.
