I just remember that I was totally clueless when I first started playing, and most of the more experienced players were very helpful and patient with me when I asked dumb questions, so I try to do the same now. Although....new players have a lot more resources nowadays than they did in vanilla. Thottbot was pretty much all we had back then, and it wasn't perfect, so it was pretty reasonable to ask random strangers for help in general chat. I don't really see random newbie questions as much anymore.
Most of the random questions I remember from back then (Vanilla days) were stuff like "where do I find _________" for some quest, because quest givers were so vague about where to go and didn't mark objective locations on the world map. You could use addons to do that, but they weren't that great and made you lag like a SOB.
Again though...I go out of my way to help newbies when they're asking for help WITHIN REASON. I draw the line at random strangers who give me the "HEY MAN CAN U RUN ME THRU DEADMINEZ PLZ??????/////" shit or ask me for tons of gold.
