As an adult, I attach my real name to just about everything (it's on my HN user page). I might not want to own everything I said as a teenager, but if you won't own what you say at 30, then when will you?

* Maybe not in the sense you mean but in a sense that I think is sufficient -- that statements from that persona can be challenged and measured against other statements in the same context for consistency.
Just recently I witnessed a heated debate between pseudonyms and the weaker of the two debaters finally said "I am Dave Foo from Sometown, Oregon - are you going to hide or man up?". The response was "I am Bill Bar from Othertown, California - what of it? You still haven't answered the questions I asked". Real names add little in terms of content of validity.
Real names aren't necessary, but if you want a reputation, you'll need to be consistent with the name you pick.
I actually like having an archive of stuff I wrote when I was 13 (and having an archive of thoughts is a prime motivator for a blog). I don't really care what people think of my 13-year-old self, especially if my current self isn't going to ever interact with them to update their beliefs. I think it was Gandhi who said "If you see a contradiction between pieces of my writing, assume I currently believe the most recent one."
For example, if you're in a conservative town and you're using your real name while arguing for civil rights for homosexuals, you might draw nutcases tracking you down and harrassing you for your simple viewpoints instead of engaging you in the medium you participated in. This isn't a matter of not owning what you say, but a matter of putting a layer of insulation between yourself and immature idiots.
Another issue with real names comes from identity theft - using real names makes the process a little easier. Real name + known site hack = half the job done.
Pseudonyms aren't just about trolling, they're also a social firewall.
A true "psuedonym" would provide you with insulation, but would follow you everywhere and you would only get one.
To say that anonymity breeds obnoxiousness baseless, especially since there is anonymity all over the web, yet 4chan is the example that everyone loves to use. Where are the other examples? What about http://en.wikipedia.org/wiki/Futaba_Channel or http://en.wikipedia.org/wiki/2channel (4chan's inspiration)? It also provides anonymity.
As pyre has already said, 4chan's b channel is a force unto itself, but there are plenty of other places with no consequences where the speech is fine and isn't the devolved miasma you make it out to be.
Pseudonyms also protect people against unwarranted discrimination. I speak as a white male with a white male name that it's fucking awesome being a white male. But I have observed those who aren't white males get subtley (and sometimes not so) discriminated against online. Check out /any/ tech post where a commenter with an Indian name takes part. Unless the Indian is well known, there's bias against their comments. Same goes for women - if the discussion is outside the 'women's sphere', watch the subtleties as some of the men close ranks. Get an openly-declared woman involved in a discussion on physics in a general forum and she won't be treated as an equal.
People should be judged on what they say, not how their name slips hints about their background. To that end, a pseudonym greatly levels the playing field.
A name, pseudonym or otherwise, merely defines a body of work, and humans are complex creatures with interests in different areas. Why should we throw away the awesome things pseduonyms do for us simply because of internet trolls - which have other effective ways of dealing with them anyway (user moderation >>> unprovable 'real name' requirement)
I don't see a big advantage to this, or at least, prefer communities where it's unnecessary. Why do you need information about how someone conducts themselves elsewhere on the net? Imo, if an online community (like any community) is functioning well, its members develop a familiarity with each other based on internal interactions.
For example, in its heydey, I knew all the regular kuro5hin posters by their k5 pseudonyms, and had positive and negative impressions of them based entirely on their k5 posting. Same with the mailing lists I'm on, the smaller (non-Reddit-sized) forums I post on, etc. Knowing external information about what they post on Slashdot or LKML or Usenet doesn't really seem necessary, and tracking people cross-websites like that even seems a bit creepy/stalkerish (unless they themselves link to their own activity elsewhere). Heck, I didn't even care if someone was a troll on Slashdot, so long as their posting on k5 was interesting.
I sort of like that one-reputation-per-community model. It does require communities that are actually communities, though, and have regulars who recognize each other. Gigantic communities with tens of thousands of transient commenters aren't really communities, so run into more problems.
