Hi.
As most of you know, you now gain experience from gathering things like herbs and ores. The same goes for Archaeology fragments. So if you are planning to get archaeology to max skill when you ding 85 - start at 80 instead. You gain LOTS of experience. I don't know if you could do this with herbalism/mining too, but even if you can you will have competition then. In arcaeology you can't have competition because all dig sites are individual.
I was bored at level 82 yesterday, so I started doing archaeology, and noticed I was gaining 9188 experience per fragment I found. At first I thought "meh", this will probably go down once the fragments become yellow/green/grey. But it never did. I don't gain skill points from fragments anymore (I am at about 105 archaeology), but I do gain 9188 exp still. So yesterday I gained about 100*9188 = 918800 experience from casually flying around while chatting with friends.
I know this is pretty common knowledge but I find it nice to be ahead in levels for the zones I am questing in. And it shouldn't take very much time to go from 80 -> 81 (the exp I gained yesterday would have taken me more than half way there) with this technique combined with a good archeology guide like this one with an addon like SAL.
