I'm not big on presentations. Where I really learn is when I can sit someone down and pick their brain about things, preferably in front of their tank. "how did you do that (pointing to xyz)? How were you able to stay on budget/ do cheaply? Where does this coral thrive best? Ect..." in an intimate setting (maybe 10 club members at a house) I'm a very methodical person, and because of that, I tend to ask some trivial and redundant questions (which I don't ask in a large group or presentation type setting.)
