Despite some cringe-worthy gaming encounters with gnomes (petrify the lot of them!), I have to support Twitch. Gnomes are good-hearted folk. A slight tendency for their more innovative experiments to blow holes in the landscape aside, they do a great job. Gnomish crossbow sights are an archer's delight and the range of alchemical tricks delight any mage hunter. My party once killed a rampaging iron golem by forting up in a gnomish shop and throwing the entire stock of acid at the construct.
Never underestimate the ability to talk to small burrowing animals either. Ever find yourself in a dungeon with a gnome PC? Look for some rats or a mole. There's a quick way to find a short cut or at worst a warning about what is around the next corner. Gnomish druids rock.
Besides, its generally only DragonLance tinker gnomes that have a consistent habit of kabooming their workshops. Its a racial flaw for that subrace. Other gnomes merely get a bit enthusiastic about chemistry. ![Big Smile [:D]](/emoticons/emotion-2.gif)
