I use my own name online. Daniel Breslauer (actually, Daniel Yehuda Breslauer) is my real name. I don't understand why so many others avoid using their real names online. What is it exactly that you are afraid of?
Are you afraid of repercussions for your children in case their schools (chedorim, yeshivos, beis yaakov, whatever) find out you are using the internet? (Regarding this, I must admit that me and my wife are just me and my wife - ie, no children yet.)
The reason for using my real identity online? I don't have anything to fear. If I don't have anything to fear, why shouldn't I use my own name online?
There are clear benefits: it's a lot easier to avoid loshon hora and related things when you are online using your real name. It's easy to call people bad things (especially in places like forums and blogs) when you don't have to fear facing any consequences. Using your real name can make you think twice: "do I really want to say this?"
I'd like to see your reasons for (not) using your real name online.
