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:

1. Links don't work in excerpts. For example, you cannot click on them to navigate to the indicated page.
2. 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.)
3. 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?).
• +1 but I think "See the corresponding Wikipedia page" is still too long & unnecessary in the wiki excerpt, this can go into the full wiki. Can you give an example of when something like that would be useful in the excerpt? – amoeba May 19 '17 at 16:26
• I suppose it isn't clear, @amoeba. My point is only that 'See the corresponding Wikipedia page' is better than https://en.wikipedia.org/wiki/Normal_distribution, not that it's a particularly good thing to add. – gung - Reinstate Monica May 19 '17 at 16:28
