Topic on Talk:Structured Discussions

I believe that Flow is being used on an opt-in basis on Wikidata and Catalan Wikipedia, and is used on user talk pages by default on MediaWiki.

Is that correct?

Are there any wikis other than MediaWiki where Flow is enabled on all talk pages by default?

Are there any wikis where Flow is widely used on an opt-in basis, even if it's not the default?

1. Yes. For more details, Flow rollout is described and documented at Flow/Rollout.
2. Not currently, but kab.wikipedia has requested it.
3. Yes, Zh.wikipedia is a particularly active wiki, per the stats at https://edit-analysis.wmflabs.org/beta-enables/#projects=testwiki,zhwiki,wikidatawiki,cawiki,urwiki,bswiki,mediawikiwiki/metrics=Flow%20Beta%20Enables
4. There's a survey coming soon, which will give more info/insight into all this.

Re #2, gom.wikipedia already has Flow on all talk pages.

Thanks!
