Anyone use it? I have a microphone but I'm afraid to use it for the obvious reason. In addition my spoken English and accent are terrible and I often can't listen to what people say with all the static sounds from crappy microphones.
Used to avoid it, started using it for arena in WoW and then continued to use voice chat in other games after I quit WoW.
Sucked at first but once you get used to it, it's alright. Having a fast paced game to use it with helps distract me a lot from thinking about what/how I'm saying something, idle conversation is more uncomfortable for me. I also don't respond well to hostility so when people are nerd raging I don't talk, which happens a lot in competitive games.
I think it can be a bit distracting. Back when I had an Xbox 360, I tried it with Halo 3, and I ended up more focused on talking to the people online instead of worrying about my score/how well I'm doing.
