My two cents: Keep it as simple as possible! And stay AWAY from Evidence Explained. I try to avoid complicated gobbledy-gook footnotes that are trying to match some academic standard.
The goal is to give the reader (who may or may not have a college education) enough information to track down the source.
For published works, title, author and year of publication are sufficient. With that much information, it's easy to do a google search and find out more if needed.
For census records: the year of the census and the locality are enough, in the text of the profile, with no need to create a footnote. Except for rare situations, there is no need to mess around with enumeration districts or page numbers, because people just search internet databases to find the census images. Here's an example of a simple census citation from the text of a profile:
William Young appears in the 1870 census in Waldwick twp., Iowa County, Wisconsin as follows: William, 60, farmer, b. Kentucky, real estate $7200, personal $1500; Susan, 42, b. Virginia; William H., 24; Mary A., 23; Eunice, 21; Abram, 19; Franklin, 17; Sarah J., 15; Celia, 13; Harvey M., 11; Lucinda, 10; Julia, 3 (all children b. Wisconsin).
Nothing more is needed -- no footnote. If the reader knows anything about genealogy, they'll be able to track down the record with that information alone.
Pet peeve: people who do "bibliography" formatting for footnotes. In my opinion:
This formal academic bibliography style is horrible for wikitree footnotes and sources:
Blow, Joe. The Genealogy of the Blow Family. Fargo, North Dakota: Privately Published, 2004. Page 23.
This is good:
Joe Blow, The Genealogy of the Blow Family (2004), p. 23.
Much of the time (especially for published works), the repository isn't needed; it's just extra clutter. If the source is a will (an example of an unpublished source) -- which of course names the jurisdiction -- a viewer will either know how to track down a will (in which case the repository information is unnecessary) or the viewer has very little knowledge of genealogy (in which case the repository information is probably not going to be useful).
Of course I'm all for including embedded links to URLs, as simple as possible: "online at [www.website.com this website]" is acceptable. Some people add "accessed 23 Nov. 2015" (or whatever date). I favor omitting that -- keep it simple!
Okay, I'm starting to sound like a broken record, and all this is just my opinion.
