Sometimes there are situations that sub-topics of a long articles are in fact redirects to the long article. In the same time, links to these sub-topics are used in the main article - which is very misleading to the readers, since it seems like there was a separate article providing more information on subtopic, but all users get is return to the top of the same article.
Hypothetical example:
The page [[Bar]] redirects to [[Foo#Bar]]. Elsewhere on page [[Foo]] there are link(s) to [[Bar]].
A real-life example:
http://en.wikipedia.org/wiki/Exodus_(band)#History
click on "Rick Hunolt" in 2nd paragraph of History section. Whoops?
What I suggest is using another colour (not red and not blue) for such self-redirects - or perhaps treating these as self-links and making them black and not clickable.
