I agree.
Both are compliments.
Here are the meanings according to the 2006 FREEREPUBLIC LEXICON (Lingo, Dictionary, Lore Handbook).
Bump is used when someone wants to post a reply to a thread simply to "bump" it back to the top of the "Latest Posts" list so more visitors will see it. It is be used to single out a comment on a thread for particular approval.
BTTT - "Back To The Top" or "Bump To The Top" is like "Bump" with an exclamation mark.
Ping is like a page. The Freeper being pinged will see the thread in "New Posts to You".
