[Yes, a date linking thread again (feel free to hate me ;-)]
Consensus about the date linking/not-linking issue is dominated by users that do have a login and can choose their date display format preferences. And I guess on en.wikipedia.org, a lot of users choose a format which is *not* the ISO-format (some hard statistics would be welcomed).
I fear this is to the detriment of anonymous users - the vast majority of our readers.
On en, it seems to be quite popular and handy to enter dates in ISO-format (Example: http://en.wikipedia.org/wiki/Template:Cite_web)
The "default date display preference" for anons for wikilinked dates entered in ISO-format is currently simply the ISO-format (no format tweaking is done).
Could/should the displayed date format of wikilinked dates that are entered in ISO-format be changed such that anons do get the same date display format that is used to show - let's say - date entries from the history of a page in a given wiki?
(I strongly assume the format of the date entries of the history of a page is configurable somewhere per wiki).
