One of the reasons could be simply because one is known under a 
nickname on a bunch of other resources where he posts to, and 
that now working for the reputation too - because posting 
something with other name could get you banned or just people 
looking with suspicious for any code and links posted.

Now, since we on D forum and that "other" world reputation 
doesn't matter here or any other reasons, some will prefer just 
using "real" name.

Some people also avoid using their work-associated emails with 
personal/fan projects. Because of same thing with 
reputation/proffesionalism/etc., (unnecesary questions from 
employer too? just a guess, whatever)

And more, and more...
Things are complicated.
