I've been using Real ID for a few months now, mostly to be able to chat cross-server with blogger or Twitter friends. Something that's come up that I find personally amusing is that whenever I add someone new, I always find myself initially torn - do I continue addressing them by their character/blogger/Twitter name? Or do I start using their now-revealed real name? I've experimented with both and in general, I ignore their real names and just continue to use whatever handle for them I'd been using before. It just feels weird to suddenly go from saying "Hey Rades" to "Hey Mike". (UH OH MY REAL NAME DON'T HACK ME D: D:)
This is not a new scenario for me, however. I've always found using real names in WoW to be an interesting conundrum, and a hard habit to get used to.
Before I joined my current guild, I would usually hang out on Vent with my brother and three close in-game friends just to chat & whatnot. Of the three, two were players we had met in-game and over time, gotten to know pretty well - well enough to know each other's real names, add each other on Facebook, etc. In Vent, these two friends and my brother all use our real names...but I still use their character names out of habit. (Not my brother - I use HIS real name, of course.)
To make things even more confusing, the 5th member of our group is my brother's co-worker, who I was introduced to as a real-life person rather than a character name, so I call HIM by his real name in Vent. He, however, addresses my brother/his co-worker by his real name, but the rest of us by our character names!
Basically, it's a ridiculous mess for any visitors (such as when we pug a raid), as some people are addressed by their real names, some are addressed as their character names, and some are addressed as both, depending on the person talking to them. :P
To confuse my head even more, when I joined my guild I discovered that they were almost all (like 95%) real-life friends. So in guild chat and Vent, they always use each other's real names because, well...they've known each other for years. It makes sense, but it sure did take some getting used to as I frantically tried to remember both everyone's names and which alts belonged to them.
Eventually I got the names locked down, and considered working my real name into our conversations so it wasn't as strange in Vent ("Hey Paul, Steve, John, Ed, Corey, and...Rades.") but as I was contemplating this, a guildie who had taken a break from the game returned - a guildie also named Mike. So rather than invite confusion, I remain Rades.
...except when I bring Mardak to raid nights, of course. And am still referred to vocally as Rades in Vent, thereby ensuring that any poor people we've pugged end up thoroughly bewildered. But the main/alt name fiasco is a whole different matter. ;)
(We did experiment with him going by Mike 1 and me going by Mike 2, but it was a disaster. Ironically, it's not the first time I've been part of a "Mike 2" naming convention. The other time was in real life with my friend/roommate Mike - our friends called him Mike 2 and called me...Walter. Yeah, I have no idea either. My friends are bizarre.)
