If you mean now, then sure I would. But there were posts and things I did when I first became a member that I’m not proud of. If I were to start with a clean slate anytime in the past two or three years then I wouldn’t have a problem. But I’m a much different person now than I was 8 years ago when I joined the SDMB. Of course the SDMB is a different place as well.
Agreed, using my first initial and last name also remind me to be circumspect, as noted upthread.
I wouldn’t want what I posted while I was drunk or stupid to come back and haunt me.
Also it keeps the urge to blast vitriol at a minimun, which coincides with the “Golden Rule” philosophy I try and adhere to.
My SDMB screen name isn’t far removed, in either of the obvious applicable senses, from my real name: it’s derived from it, and you’d have to be a total Googleklutz to fail to obtain my real name on short order were you inclined to want it. So no, I’m about as ‘onymous’ this way as I would be if I posted by my real name.
I don’t badmouth my boss or clients too much here (far less than I do in front of a sympathetic co-worker), and never by name, but if I were posting under my real name I’d probably cut out even that small amount. I realize that someone really determined could find out who I am pretty easily, but my boss is not net-savvy and my clients are not determined, so the userID adds a layer of deniability. “How many ad copywriter/wedding ministers can there be in Tokyo?” “I dunno, but that ain’t me.”
I don’t post anything that I wouldn’t practially tell anyone anyway. I try not to say anything about my working conditions anyway because I’d rather not have anything come back and bite me in the ass, but that’s about it.
Besides, even if someone had my first and last name, even the city I live in, you probably wouldn’t be able to find my anyway since my name is so very, very common, and I’m not in the phone book.
It wouldn’t be hard to find me (at least my office) from what I’ve posted already. I also used to sign my posts with my first name. So no, I can’t think of anything I would change about my posts even if my real name were attatched to them.
Like What Exit?, I started out here using my real name as my user name and then changed it pretty quickly to my current herpetological appellation. Like some others, my real name can be discovered pretty easily, without leaving this site. When I changed my name, I wasn’t seeking airtight anonymity. My intention was to be anonymous to the random browser, an acquaintance or coworker who might stumble onto SDMB, see my name, and decide to look at all of my posts to see what I had to say.
If I had been unable to change my user name when I did, I believe my posting history would be as it is now.
The email address I use here is also my real name. Machume Hotmail, at your service.
As it is now, I don’t post some things that I want to because I use this name everywhere. I have some secrets that I would love to blab to you guys, but don’t want my friends to know. 
If I used my real name, I’d be quite easy to find. There are only 2 or 3 “me’s” in the country.
And this is where you fled for safety? 
Oh, and my name’s Ben Duffy.
About the only thing I’d change is stuff I post about a few of my coworkers, Roundboy and Mandy the martian. I don’t post anything about them that I haven’t referenced to them personally, but I tend to exaggerate (but don’t lie about) their antics here. It’s just that I see no reason to cause potential professional embarassment to those clowns gentle souls.
There’s only one or two “me’s” in the country, so I would be loathe to use my full real name.
Y’know, I’ve sometimes wondered the same thing myself WRT to this board and other Dopers.
I can’t imagine that I’d change a single thing about what I’ve posted on the SDMB, or would post in the future. Apart from my shyness (or, depending on your point of view, my just-under-the-surface misanthropy), I’m generally an open book, and to the degree that I’m not, it’s not because I’m unduly ashamed of any opinions that I hold or any (harmless) aspects of my personality. Furthermore, I’m not an open book to the degree that there could be some stuff that I wouldn’t share with anyone, either as myself (IRL) or semi-anonymously (on the SDMB).
Could someone who knows me IRL figure out my real life identity by reading my posts?
Well, with the exception of my family of origin (and, even then, not all of them), no one IRL knows me by my username. Even those who do don’t usually refer to me by it, but yeah, I believe that, if any of them were to read these boards, they’d know instantly, and beyond any doubt, who the poster was. And some of 'em wouldn’t be too amused with some of what I’ve shared here, but as they are well aware, how they feel about how I live my life is not my concern, either here or IRL.
People who know me fairly well, but who don’t know me by my username, could probably, given a little time, figure out who I am by reading my posts. The thing is, the only person who I believe knows about my activities here is one of my work friends (I often read the SDMB during downtime at work, and she teases me because I often print out some threads to read during my commute (no, she doesn’t know my handle)). Neither my family nor my close friends know because, WRT my family of origin, we seem, more often than not, to operate on vastly different planes of existence that I don’t tell them much of anything about my life (not that there’s much that wouldn’t offend their sensibilities, mind you, which is precisely why we’re not close), and, WRT my family of choice (the ones to whom I tell most of my shit), I speak with them so rarely (unfortunately) that, when we do connect, we speak about so many other things that the SDMB doesn’t come up in conversation.
So, no, wouldn’t change a thing.
I would post differently. I used to be sort of anonymity-phobic when I was a teacher, hoping non of my students would find out who I was. Then I left academia and am much less worried about it. Personally, I think having a certain amount of anonymity allows for one to be alittle more free in what they say…and to blather about when they would normally have more restraint…Or mayeb that’s just me 
Nope. It’s not hard to figure out who I am from my posts (and even if it were, I’d still assume it would still be possible), so I’ve always behaved as if people knew. There’s a touch more shade here than in real life, but I still operate on the assumption that my identity might become available. I think it’s wise for anyone to act in the same fashion – as long as someone’s archiving, your whole past posting behavior can become known. So don’t bad-mouth your bosses or name names.
I’m still waiting for your next book Cal. My wife and I enjoyed the Gorgon one.
Eh, of course I would. I would honestly not mind if my name and address was beside every post. I don’t post unless I feel I contribute though, and I am not often involved in ranting, political arguments, or the like, but I enjoy this board so much that I’m pretty sure if anyone contacted me from here I’d be glad to talk to them.

I think I sort of like anonymity. (Sometimes I think about moving to the middle of nowhere and starting from scratch…)
CaerieD’s comments apply to me pretty well in their entirety.
I use the same name in most places, so I reckon anybody I know IRL who happened to find the SDMB (easy, as I have mentioned it to a few people) might think “hmm, I wonder if that is the same Celyn”. I don’t tend to put private stuff on the boards, though, and I suppose that IS partly because, dammit, blew my cover already.
