Eek. Be careful with Gtalk or maybe Adium. I reached out to my friend in Australia, Stephen Collins (@trib), to ask him a question. Although he appeared to me on my IM client, adium, as Stephen Collins, it soon became obvious I was not talking to Stephen. Gtalk had somehow switched identities to another friend of mine, Jeanne Bissell-Privett in Ohio. Could have been really embarrassing. Sailors take warning!
