I don't use the "See also" heading because many of the items I want to list in the Sources section are not "see also" items, but documents that are cited in multiple inline notes in the profile, with different pages cited (or different text included) in different notes.
On a Wiki, we can't depend on footnotes always remaining in their current sequence, and we can't assume that the first note that cites a particular source document will always be the first citation to that source document (or will not be removed by a future edit). Therefore, instead of putting the full citation details into the first note (and hoping that the current profile structure will stay intact forever), I like to provide a full citation in the Sources section and use shorter citations in the inline notes. And I like for the list of sources cited to be alphabetical because that makes it easier to find a specific item.
