Thread:Translating talk:MediaWiki/Helpful vs. Useful/reply (4)

There's less a difference in meaning, than there is in "results": both are used to evaluate how interesting the submitted feedback is.

Readers (anonymous, unconfirmed users) can only mark posts as helpful/unhelpful (and mark as abusive) Registered, confirmed users do not have these helpful/unhelpful tools, but a more detailed "useful/resolved/non-actionable/inappropriate" (and hide/request oversight/oversight)

All actions performed by registered users will be reflected in the different filters (view all "useful/resolved/...' posts) and will result in the feedback no longer being displayed in the "unmoderated" queue. Actions performed by readers will not have such effect: that feedback will still show up in the "unreviewed" queue. It will only help surface useful feedback in a "featured" filter.

Basically, helpful (for readers) and useful (for registered users) are pretty much the same in meaning, but for a different user group and with different effects.
