Since so many of us are, I'm curious as to what our motives are.
I'm also curious as to what kind of veggie you are (plain veggie, vegan, lacto, ovo, etc.) I'm a pesco-veggie (I eat fish, plus the regular veggie diet, but no meat, chicken, eggs, etc)
I am really because of the health benefits. The philosophical cruelty argument has never really resonated with me, probably because I am an ecologist by trade and we, as human animals, fit into the food chain with everyone else. (of course not the extreme stuff like testing bath products on animals, but just the concept of eating a living thing) But the health benefits of vegetarianism are really striking. When you compound that with the terrible treatment of commercial meat, much of which puts consumers at risk, I find the veggie life very superior to a carnivorous one.
