When creating or updating / improving a tag wiki excerpt, should a link (e.g., to Wikipedia) be appended to the end? Note that I am not referring to the full wiki for a tag, I am only asking about the excerpt.
It seems to me that links are best not included in excerpts (of course, they do make sense in a full wiki). I think they should not be included for the following reasons:
- Links don't work in excerpts. For example, you cannot click on them to navigate to the indicated page.
- They are hard to read. It would be cleaner to put, 'See the corresponding Wikipedia page' than (say)
https://en.wikipedia.org/wiki/Normal_distribution. (I'm not necessarily arguing we should put 'See the corresponding Wikipedia page', only that it's easier to read.)
- Our general policy for excerpts is to keep them as short as possible while still covering what needs to be covered (see: What is the optimal length & level of detail of tag wiki excerpts?).
