Hi,
I often stumble over /Talk pages containing requests for changes, clarification, or similar, which are outdated by the main page's progress. An example of many is URL:http://www.wikipedia.com/wiki.cgi?action=browse&id=LISP_programming_language/Talk&revision=1:
Page for discussion ...
Fluff, removed now.
"... and is therefore the oldest programming language ..."
with arguments why this is false. Notion has been corrected in the article. Following is a section acknowledging the error.
"... and CDR (Contents of Address Register) ..."
Pointing out a typo, which has been fixed. Another section acknowledging this error follows.
Function CAR in LISP program returns ...
I don't know what this is, perhaps a suggested addition to the article?
So, one section is still relevant, the other four or five were used by people to showcase problems that they were not sure enough about to go ahead and correct them. I'm unsure what should be done about these no-longer-relevant bits.
My preferred alternative is deleting them outright, and make the following guideline: If you implement a suggestion from a /Talk page, be sure to delete the suggestion as well. It is no longer relevant to the current revision of the article.
The counter argument that holds me back is that the discussion provides background reasoning to changes, especially regarding more contentious topics.
(Obviously this does not apply to the CAR/CDR change, so I decided to remove that as well, now.)
Thoughts?
