For example if there is a search result or someone sends a "funny" link,
my motivation to follow the link by sure depends on whether it pretends
to be a .jpg, .doc, .ppt, .pdf or unpredictable filetype where I only
know that it is a html if I know that the destination site is a
DokuWiki, and in this case no ending means actually html.


Why? As Andreas said, file name extensions have no meaning on the Web. Just
because a link ends in ".jpg" doesn't mean it is a JPEG; just because it ends
in ".html" doesn't mean it's HTML. (Yes, I've seen actual ".jpg" links in the
wild that point to quite different things.) There's nothing in a link itself
that can tell you what file type it points to. This can only be conveyed
through meta information -- be it a Content-Type header, or the
trustworthyness of the sender of the funny link. (And in email, without good
use of encryption, you can't even be sure it came from who it says ;))

To be nice to wary users, HTML let's you provide a type attribute to <a>. But
that's just a service for the user, and most users won't ever know, because
most browsers do nothing useful with it.



One advantage of adding an extension is that if you do a "wget 
http://wiki.../some_file.html";
or curl etc, that it gets saved automatically with the right extention, ready
to be clicked on when presented in a list by a e.g. windows explorer.
