Yeah....they might indeed find the forum, but I seriously doubt many will create an account and post much.  Children are like aliens to me, but from what I've heard about them they're very much into other social media sites and would probably find bitcointalk to be the equivalent of trying to read a newspaper.  And I mean a real, physical, makes-your-fingers-black, newspaper.  It's something that won't appeal to youngsters.

And even if minors did find the forum and stick around, it's not as though every thread is infested with profanity or obscene material.  What they'd really have to worry about is getting scammed, not picking up some bad habits or bad language.  LoyceV is right that school is much worse than bitcointalk.  You can't get your ass beat here.  Nobody can wipe boogers on you or whip you with a wet towel in the locker room.  I mean, please.  Let's keep things in perspective here FFS.

Where is TMAN, by the way?
