Something that I really appreciate after moving here from Reddit: I can finally edit titles!
No more having to delete and re-post when I notice a typo. No more having to endure the embarrassment when I don’t notice one until after the comments have already started.
It’s a small thing, but a relief nevertheless.
Other than the harmful “prank” type thing where you start with one title, gather comments and then edit it to make those comments mean something completely different, there is still the problem of creating an external link, getting the post to the top of hot/active/whatever and editing the URL to point somewhere malicious.
The counterpoint which usually is “you can already do that with short url services”, to which the answer is “That’s why they were all banned on Reddit”.
Especially as there is absolutely no indication on Kbin that the title has been edited anywhere, and on Lemmy it’s only that tiny pencil next to the post age.
