Interesting thread, this! I'd like to think i do, i just enjoy it and am generally a bit pissed-up before we go on anyway so it all works out nicely for having fun
Interaction with the rest of the band/ anyone watching is really important for me, I remember the first few gigs i did i was pretty wooden with next to no crowd interaction, but after meeting Dave (frontman of my current band who swings about like something fresh out of the 60's and had been doing it considerably longer than me) it all kinda made sense. I still think he over does it sometimes, but then i guess that's natural for anyone playing the cool-geezer-on-bass role to think that! I like playing with the crowd too, seeing what kind of reactions you can get out of them, it relaxes me.
Definitely feel that live shows, when they're going right, are one of those times when you can just really lose yourself in, have fun with the people who are there at that moment and not really care too much about how perfect your playing is. That's what the studio's for!
