I’m 25.
I’m curious: Why do you ask?

I’m 16. I use “chat lingo” or “AOL speak” occasionally, but usually as a joke, or to make a point.
I am 21, and I’ve been here since I was 17. Hopefully it hasn’t been too easy to tell my age (although for the first month or so I was prone to writing without use of SHIFT). The extent of my “l33t” use is for humorous effect or in the phrase “teh r0xx0rs” (well, teh anything-0rs, really; I overuse “0rs”).
23 here. I hope someday to mature into someone who can spell.

I’m 21 with 8 years experience. 
All those acronyms drive me crazy.
I had to ask my older sister what the heck YMMV meant the other day.
Is there a thread that breaks these all down? A sticky would be helpful, FWIW. 
There are multiple threads that explain abbreviations. Several of them can be found listed in this thread.
Much obliged, Mr/Ms 12,000 + post.
You would know! 
I’m 14.
I suspect that I might be the youngest member here. Is anyone younger than 14?

Haha, I’m the same boat! I’m actually highly critical of people younger than me, shaking my head at where our generation is headed. Mean, huh?
I think even my sister has grown to have a similar attitude. She’s 16 and thinks a lot of kids her age are shallow and stupid. 
Oh yeah, I’m 20, but I am an old soul in some ways.
I’m 25. If only for a few more weeks.
Now you’ve reminded me to post in the Time to celebrate May Straight Dope birthdays! thread
Stick around. I think you’ll like it here.
I’m 20. Like many of the younger Dopers here, I can’t stand most of the members of my age group. Then again, I grew up fairly quickly (which is yet another common trait among SDMB folk…wonder why so many of us end up here? ), even if it took me a few extra years to realize I had done so.
uhhh let me guess… ‘FairyChat’?
Are you the youngest mod?
My eternally 23 year old brain keeps making promises that my 55 year old body is having extreme difficulty keeping. Does that count?
Hey, Clothahump – it could be worse. You could be like me and have a 55-year-old body that kvetches like it’s 70.
START, I can sign you up whenever you like – I did it for over a dozen Dopers during the initial switch to paid subscriptions. Just email me at laura.graf@comcast.net, and we can arrange the details.
Hey, START – will you please join the Dope

All the fruits of this mind-widening fray.
It may make us mad,
Or be funny or sad,
But there’s always so much more to say!
There was once a thread in which some of our fine SDMB statisticians(and there are none finer) calculated the age of the average doper to be 31.5 years. I’m not certain what significance that has, but you asked. Yes you did. Kinda’.
There was also a thread about how many teenagers were posters, and the youngest poster. At the time, several said they were 13, which is the minimum age required to register.
One member posted a complicated formula to reveal her age. The answer worked out to 12, but I guess the mods didn’t bother to do the math as she wasn’t banned.
Welcome, and do join up.
One of the advantages of advanced age is seeing this sort of comment often enough to avoid repeating it.
There are all sorts of people of all ages who are immature. I can remember listening to my (30-something) boss telling me (mid 20s) how sad it was that “today’s kids” didn’t have the same work ethic that we had (despite the fact that he had several very responsible teens on his staff). I have watched one woman who was known to her managers as a complete slacker go off to be a manager at a different site and begin bitching that “today’s kids” did not have any sense of responsibility. (And the “kids” about whom she complained are now complaining about the “kids” that they supervise.)
It is true that the demands of advancing age (as one accumulates spouses, mortgages, children, and infirmities) tends to compel certain people to become more responsible as they age, but any broad claim that any age group can be universally characterized as frivolous, giddy, serious, overbearing, stuffy, or mature will shatter on the many exceptions that can be found among its members.
I was at a party where my daughter’s high school religion class invited the parish’s senior group. We were playing some historical trivia game (not Trivial Pursuit, but with similar questions) and I was shocked that only one of the teen players knew most of the answers–but then I noticed that I was the only adult who knew the answers–and many of the questions were from the period before I entered school and about the time the seniors would have been leaving college and being able to vote.
