I'm curious if your plans are for a Wikimedia wiki, Felipe?
Since people are pointing out learnings from similar experiments, I
would like to add another one:
https://www.mediawiki.org/wiki/Article_feedback/Version_5. There are a
lot of subpages with a lot of information.
ArticleFeedback version 5 added a comment box at the end of every
article. It was highly "successful" in so far that people used it a
lot. A lot of the comments said something like "finally I can leave
comments on Wikipedia articles". Like talk pages would not exist.
Something like 95% of the comments added this way are entirely
inactionable (e.g. asking for things that are already in the article),
and the rest of questionable value.
Kind regards
Thiemo
