This is an interesting topic. For me, there is no difference between who I am "online" and who I am "in real life". Let me explain a bit; I used to play a lot of World of Warcraft and when I did, I blogged about it and then was a fairly popular WoW blogger. Seriously, I had over one thousand subscribers at one point. I made a twitter and promptly had over a thousand twitter followers. Etc.

Anyways the twitter was mostly (but not exclusively) WoW themed and I added a lot of fellow WoW bloggers/players, and I soon noticed a trend among them where a lot of them had two twitter accounts, one for video games and one for "IRL". I never quite "got" that. I am who I am, and who I am is a nerd who plays a ridiculous amount of video games and writes about them (currently for a different and non-WoW-focused blog, but!) I don't really care who finds out, because I'm very open and proud about who I am. If someone looks down on me for it, I don't care.

So yeah, it all overlaps for me.
