> DD is not defined (one would have to go to the main page) and it is not a well known acronym.

Worst, in the industry its often an acronym for "drawdown". I was quite confused until I saw the definition DD=due diligence on the homepage.

I've been in the industry for several years and had the same reaction when I first starting seeing wallstreetbets posts. For a while I even thought it stood for "double down" when it seemed like these were encouraging posts. Good point from you and the parent commenter -- I'll make that clearer.
