The only thing that bothers me about Yahoo live is this, I have chatted live in the past and really enjoyed getting to know some of the guys in the biz, but if I choose not to log on and chat for what ever reason, they are some who choose to use "Excessive Vulgarity to the guests.
You have know idea who these guests are, they could be potential customers and if they are like me, they will research the person and their company that is cursing them out and rest assured for what little its worth, they will not get the job or respect we try so hard to receive from our peers.
Personally when someone curses me (guest) before I sign in, Its going to be a given that I don't sign in and join in carry on a civil conversation with that person.
