people think that withyout going enom that others will know who they are, or they might give an answer that is rubbish and people respond to that, but without being anom, its a personal attack, so they use the anom because there's no real effort in a question or answer or they are so imbarrassed to ask that question, they need to hide. It cannot be anything else but lack of balls and just very very wimpish maybe.
If it is something I'm very self conscious about, and I don't want any private messages from intrusive creepy people trying to prod more information out of me, then I'll go anonymous. If it's something I really don't want anybody ever finding out about me, I'll go anonymous.
If there was no anonymous button, I wouldn't be as likely to disclose nearly as much information.
Honestly, I go anonymous because there's some crazy people online who, if you actually voice your opinion and give them a reality check about their situation, will stalk you and send you threatening messages and so forth.
It didn't really bother me, but holy sh*t, was it annoying.
So, to avoid any further rubbish like that, I will go anonymous, particularly if the QA is anonymous himself/herself.
It changes nothing for me because I've never used the anon feature, lol. I figure if I don't feel comfortable saying something with my own 'face' showing, then it's probably not anything worth saying. =]
Wouldn't matter to me either way. I go anonymous sometimes when I ask questions to get unbiased answers. I've only ever answered a few questions anonymously though and they were mostly sexual so I wouldn't get pervs creeping me.
