I like to be anonymous. In fact, I wish now that I had used anonymous as my username, or perhaps anonymouse. or if you want to keep it really simple, anon.
Most of us don't use the whole name anyway. Lots of people call me star (which I am of course)(tee hee). I would just call him or her besty if I was answering a question.
If you are using Firefox the add-on CoLT adds a copy link text to the context menu when you right-click on a username (since it is a link) and so you just then copy and paste it into your text; that's what I use and it saves a bit of typing.
