As has been the sentiment in past posts, I don't hate young people, just people who act retarded. My guild leader is 15. That's young to me. That said, he's one of the nicest guys around- helps out lowbies, runs the guild like a well oiled machine, is friendly (i.e. has the option turned on so that he can greet everyone as soon as they sign on), and runs guild auctions and other stuff. When I found out he was young I didn't just quit the guild, frankly I was impressed that a 15 year old was that competent.
That said, for every young player who has a good head on their shoulders, knows basic rules of grammar and spells reasonably well, there are at least 5 utterly worthless people. What makes me able to judge people as worthless? Glad you asked:
Meet newb X. X is a lowbie who I am helping through some quests. As soon as he sees chests, he stops fighting mobs and runs for it, opens it, and ninjas the loot. Fine. I explain to him the principles of sharing and basic WoW etiquette. He then exclaims in guildchat that I'm an elitest who's yelling at him to play the game how I want it played. K... I suggest to him talents, how to use the AH...seriously, I must've spent 2 hours helping this kid. Oh, did I mention he only typed in caps, fractured english (not english as a second language, I mean white kid ghetto english), and couldn't spell to save his soul? Yeah...
So it gets better. Next day he signs on, asks me how to "CRE8 1 OF DOS MAKRO TINGS" (which took me a few seconds to translate). I told him, using /w as an example, how to make a text macro. He then proceeds to "test" out the macro technique by saying, in g-chat, "THIS GUILD HAS DRUGGIES" 15 times in succession. Everyone loved him after that.
Better still- the guildmaster wasn't online during that period. The kid signs out for an hour. Guildmaster comes back (I tell him of our friend...he's unhappy). Kid signs on. In g-chat, this is exactly what happened:
Kid X: O_o DOODS CHEK DIS OUT!!
Guildmember: Dude...stop typing in all caps, seriously
Kid X: SHUDAP NEWB
Kid X: SERIUSLY I FOUND THE BEST MOD EVAR
Kid X: IT MAKES EVRYTING I TYPE GO TO 1337 SPEAK!!!
Guildmaster: No, no and no
*Kid X has left the guild*
Guildmaster: booting him was the best decision I've ever made in my life. Ever.
