Random notes: I always try to see what I like in talks so I can emulate them. Today I noticed a number of speakers for whom confidence and careful, practiced wording went a long way, even on talks where the concepts were very difficult.
Favourite quotes (unattributed for anonymity):
Use of "2 cents" to title that section where you extrapolate your results to bigger-picture discussion.
"Community ecologists always want more than two species, although, two species is a good starting point." (absolutely!)
"The data isn't very good; it doesn't support the model"
