Yep, Squire uses pick almost exclusively. I believe Cliff Burton (metallica's original bassist) did too. Both were Ric users too, come to think of it...
Plectrum is just another tool in your arsenal; it's good to know if you need it. They make big felt picks if you want a softer attack, not as clicky. Or you can roll off some highs. As long as you think like a bassist and not a guitarist you can find the pocket even with a pick. (not that I'm advocating it)
wait till you discover fretless!
we've got some custom bass-based instruments coming from a Dutch luthier soon, the first one's done and almost ready to ship. It's pretty funky.
dangit! You guys are getting me jonesin' for bass again!
Should we do another Bass Summit for the gulf coast? Last one was fun.
