Hello Org experts,

I want to auto insert a title from an HTML page as description for an org link 
in
my notes. I stumbled upon some old message by Miro Bezjak on this list:

https://lists.gnu.org/archive/html/emacs-orgmode/2012-09/msg01435.html

I have seen the replies, but I am not sure how to use
org-make-link-description-function, so I coded my own version of Miros idea:

#+begin_src emacs-lisp
(defun org-link-from-clipboard ()
  "Insert an org link into current buffer from an URL in clipboard."
  (interactive)
  (let ((marker (point-marker))
        (url
         (if (string-match-p "^\\(http\\|https\\)://" (current-kill 0))
             (current-kill 0)
           (read-string "URL: ")))
        (title nil))
    (when url
      (url-retrieve url
       (lambda (buffer)
         (goto-char (point-min))
         (when (re-search-forward "<title>\\(.*\\)</title>" nil t)
           (setq title (string-trim (match-string-no-properties 1))))
         (with-current-buffer (marker-buffer marker)
           (save-excursion
             (goto-char (marker-position marker))
             (org-insert-link
              nil url (or title (read-string "Description: "))))))
       nil t t))))
#+end_src

While my function is not very big, I would still like to learn how to use the
suggested built-in stuff from that discussion. I also dislike the interactive
fallback in asynchronous callback if the title is not found, but I would also
dislike to have a bunch of "No description found" strings in my notes too, so I
am not sure which one is less evil there.

Thankful for any help and advice.
