WoW is not like a free MMO where everyone is noisy and chatty. Ppl in WoW are more demanding when it comes to common courtesy and how you treat other players.
If you're asking for help a lot in the general channel, you might not be so welcomed. Some ppl will help but most people do not bother because they do not want to help i.e. bz with their own quests and they don't want to share quest with others.
It's not too hard in the starting areas up to level 20. After that, it's slightly more difficult but not so much.
Just remember that this isn't like RO or those Free MMOs where it's normal to shout for help all the time. If you do that in WoW, you get told off very harshly and you might carry the n00b label until you're up to lvl70.
I'd suggest u do a bit of time reading on www.wowwiki.com and www.wowhead.com .
You probably won't get someone to help u quest but if u need to know where to look for a mob, usually someone will say something. And it gets more interesting once you start off your first dungeon run.
