One thing I like about the www is no matter what they subject, somebody's discussing it. Glad I found this page.
I don't necessarily mind when the word is used verbally- "Hey there, how are you doing?" or "Hey Bob, over here!!" but it sets my teeth on edge when it's used to address someone in emails, on forums, and in texts, and from my experiences it always comes from individuals who are not known to the recipient.
