I love tweaking Emacs to fit the way I work. Here's some code to make it easier to keep track of pinged people.

(defun sacha/bbdb-ping-bbdb-record (bbdb-record text &optional date regrind)
  "Adds a note for today to the current BBDB record.
Call with a prefix to specify date."
  (interactive (list (bbdb-current-record t)
                     (read-string "Notes: ")
                     (if current-prefix-arg (planner-read-date) (planner-today))
                     t))
  (bbdb-record-set-notes bbdb-record (concat date ": " text "\n" (bbdb-record-notes bbdb-record)))
  (if regrind
      (save-excursion
        (set-buffer bbdb-buffer-name)
        (bbdb-redisplay-one-record bbdb-record)))
  nil)

(defun sacha/bbdb-gnus-ping (text)
  "Add a ping for authors/recipients of this message.
Call with a prefix to specify a manual note."
  (interactive (list (if current-prefix-arg (read-string "Notes: "))))
  (let* ((from-me-p
          (string-match gnus-ignored-from-addresses
                        (message-fetch-field "From")))
         (bbdb-get-only-first-address-p nil)
         (bbdb-get-addresses-headers
          (list (assoc (if from-me-p 'recipients 'authors) bbdb-get-addresses-headers)))
         (bbdb/gnus-update-records-mode 'annotating)
         (bbdb-message-cache nil)
         (bbdb-user-mail-names nil)
         (gnus-ignored-from-addresses nil)
         records)
    (setq records (bbdb/gnus-update-records t))
    (if records
        (bbdb-display-records records)
      (bbdb-undisplay-records))
    (while records
      (sacha/bbdb-ping-bbdb-record
       (car records)
       (concat
        (if from-me-p "-> " "<- ")
        (or text (message-fetch-field "Subject")))
       (planner-date-to-filename
        (date-to-time (message-fetch-field "Date"))))
      (setq records (cdr records)))
    (setq records (bbdb/gnus-update-records t))
    (if records
        (bbdb-display-records records)
      (bbdb-undisplay-records))))
