Everybody probably holds a pick slightly differently.
I use the side of the pick instead of the pointy part cause it's easier to hold on to and ya get more bite out of the softer picks.
When I'm using an acoustic though, I switch to a larger, lighter pick so you can hear the 'clicking' sound and play heavier without drowning everything else out.

I keep a big wooden bowl (that I made on a lathe in Junior High :) on my mixer filled with all kindsa different types of picks. everything from small hard ones, to huge leather ones. That way you can play around until you find the right sound.

(It's also a great bowl for holding peanuts when you're drinking beer but that's another story).
