A profile address that does not belong to anyone now takes you to a proper not-found page. Before, a mistyped or deleted username loaded a page that technically reported success while showing you a "not found" line — which looked fine in a browser but told search engines and link checkers that a dead address was a real page. The page now says the username does not belong to an account, and says it in a way that anything visiting the address can tell apart from a real profile.

Every page now has a title that says what it is. Until now a browser tab, a bookmark and a shared link all read simply "Proposit", whichever page you were on — so a row of open tabs told you nothing, and a saved bookmark was unfindable a week later. Explore, the community guidelines, the terms, the privacy policy, support, sign-in, sign-up and reporting each name themselves now, and a profile page names whose arguments you are looking at.

Argument pages that had a summary written for them now show it when the page is shared, instead of falling back to the same generic line as everything else.

A handful of places that were meant to show a stand-in label — "(untitled premise)", "Anonymous", a reason a button is unavailable — went blank instead when the real value was empty. They show the stand-in now. And a sign-in link that carried an empty "return here afterwards" destination used to leave you where you started rather than taking you to your profile.

An argument page now arrives with the argument already on it. Before, opening one meant waiting through a placeholder while the browser downloaded and ran the page's code, and anything that could not run that code — a search engine, a link preview, a reader with JavaScript turned off — saw only an empty frame. The claims, the premises and the title are now in the very first response, and the interactive parts settle in a moment later.

Showcase arguments now say where they came from. Each one is a formal reconstruction of a canonical work — On Liberty, the Crito — and the page now names the author, describes the original text, and explains what Proposit added to it, right below the argument itself. That was previously only visible if you opened the sidebar.

Reviewing an argument that cites sources no longer opens on a blank card. The review walk asks you to judge each claim in turn, but every source attached to a claim was being counted as a claim of its own — and a source has no wording to show you, so those steps arrived empty, with nothing to read and only True, False and Unknown underneath. On most arguments that cite anything, it was the first thing you saw. The walk now covers only the claims someone actually wrote, so it starts on something readable and is as long as the argument has claims. The sources themselves are unchanged: they are still listed on the claim they back, where you can read them while deciding.

Published arguments can now appear in Google Search. Showcase arguments are listed as soon as they go up. Everything else is listed a day after it is published — a deliberate pause, so anything that needs removing can be dealt with before a search engine has seen it. Nothing about that first day is different for a reader: the argument is exactly as visible and as shareable as before, and a link you send works the same way. It is simply not in Google yet.
