Anonymity can sometimes be very liberating. Maybe when I become a better writer or my startup is wildly successful I will reveal my identity. Until then I don't see why I should silence my most authentic voice by closing this account or use my real name on every comment that I write. What's wrong with using a pseudonym once in awhile? Some people only use a pseudonym - is that so wrong?
I treat this account more like a diary. I take more risks under this account. It grants me creative license to be myself but not the self I want shown when someone googles me.
What if my startup doesn't work out? I'm going to need a "real job" and if the economic environment gets much worse I might find myself interviewing with a conservative pointy-haired boss. This is a real life possibility and if it turns out that is what happens I'm better off if my interviewer hasn't read my honest ramblings on corporate life, sex, philosophy, politics - all of which I feel free to discuss under a pseudonym. Look at it another way: in a worst-case-scenario, let's assume one day I am wrongly accused of a terrible crime - do I want the prosecutor to take out of context my most controversial, intimate musings? There are after all some things you can't say. I haven't exposed much under this account - I just started it a few weeks ago - but <edit>my reaction to the negativity in this thread</edit> is What is wrong with someone detaching themselves a bit from their ego? <edit>Downmodders,</edit> how am I hurting the community?
For me, it boils down to this: a goal of the site is to improve quality of discussion.
There are two main parties to discussion: "you", and "everyone else".
When "you" post: if you already suspect that your topic will earn down-votes, then why post it (from any account)? Apparently the topic is not something interesting to this group.
When "everyone else" down-votes: they have a responsibility to be smart, and not childish. It's shallow to click the down-arrow simply for disagreeing with somebody or not liking them personally. If there is a general feeling that down-votes are always for legitimate reason, I think people would be less likely to "hide" behind anonymous accounts.
Most of the time I post under my real name (actually, I don't know why I'm using a pseudonym on HN, frankly, just reflex when I first joined).
The exceptions are: Discussions on Politics or Religion. I don't want my name associated with any religious (or atheist) group nor do I want it associated with any particular political party. I have worked for people that once they discovered my political views, I was treated differently because we either agreed or disagreed. I know that my name is going to be googled the next time I apply for a job and could run into someone who will toss out my resume simply because I'm conservative, liberal or other.
If a site is overly political, or it's associated with a political cause, I will always keep only one ID on that site. If the site allows anonymous posting, I'll use my real name and post anonymously when broaching a subject that is controversial. If the site does not allow anonymous posting, I'll keep two IDs handy for when I want to join into discussions that would identify my political or (non/religious) affiliation.
Everything I post, I'd be OK seeing it on the 6 o'clock news. But then, I'd expect that as I ran for election last November.
Why would you go through the trouble? Why not refrain from posting it when you think it is questionable?
