Even if the room's near empty, you never can tell how many people will watch a recorded conference talk online. I don't know about other folks, but I can rarely get out to conferences for time/money/family reasons, but I'll often watch the talks online. If you give a good talk and it's recorded and online, with luck you'll eventually find an audience.
