The problem is, not everyone is comfortable with sharing information online, as you'll never know who will be looking at those information, especially female gamers which seem to be extremely rare. It could be your employee, your wife to some psychopath looking at those information.
It could be ok for you to put your real name online, i, for one, im not comfortable with it,even on my own Facebook, as Mark Zuckerberg is quite infamous for leaking out private information to anyone or doesnt care about your privacy on Facebook. Internet isnt a place to store private information, IMO. I rather keep them on a piece of paper than on the net.
As it was shown, anyone could easily dig up tonnes of information easily, not just about you, also about your friends and family. I dont want to see my family involved in something unpleasant due to some of my posts arguing about some epic loot in the new Battlenet forums. The way Blizzard is doing seems pretty much asking some murder over some loot to happen.
Maybe just first name, but hide the surname, or maybe some other could work. Or maybe give us an option to hide the name, and only show the Battlenet nick name. Showing Battlenet nick name isnt as bad as compulsory to show your first and last name on every single post you make on the forums. What happens if Blizzard extent it to the rest of the Battlenet, as it seems like a good idea to Blizzard.
To be honest, what Blizzard is doing now, with all these Real ID thing, doesnt seem like a well thought out decision. It also resembles a lot with MW2's no dedicated server issue, as the reasoning Blizzard is putting, doesnt make any sense and it looks like, they just dont care. As they just gonna lose some, and gain much more. Just like MW2, "whiny" "dedicated server lovers" hardcores are either staying in CoD4 or move on to other games like BFBC2. This could happen again.
Could be a good opportunity for the new Star Wars MMO or Warhammer 40k MMO. Also, 10000+ post in less than 24 hours, wow, they are pissed.

Something from Kotaku.
The reasoning behind the real id is decent: To make you think before you post, but the problem is, is it at the expense of your privacy?
