I've gone anonymous probably about 4 times total. One was a question, and the others were when I typed opinions, felt completely stupid about them afterwards, and hid my face in shame by clicking "anonymous." I don't like going anonymous so I try to avoid it.
Not as often as before, which is also why people tend to randomly block me for my views on Justin Bieber or any other types of fanatism. In fact, I am proud of my beliefs and views, as they are my own, rather than having had them chosen for me so that I would need to verify and defend it even for myself.
Sometimes some questions I ask are a bit controversial, in those cases being anonymous makes sense. No hard feelings or anything, it's just different if it is anonymous rather than my identity here.
I have Asked a Question in Incognito, @vivavila, and even have Answered a couple when it came to Hot spots such as Politics and Religion. I find that with These two sore subjects, some people lock horns with This, and tis sometimes better to be an Unknown than to Be Known as a sore loser for Showing your face in their place and having to Block them when they Get.. Out of place. Good luck. xx
