My tip is one of common sense rather than genius.
Being short (in more ways than one) of common sense I made the mistake of selling everything I picked up to vendors to get my bags empty in order that I could hurry back to questing. I thought this method saved me valuable time at the auction house and that I would level more quickly.
I couldn’t afford the gear I needed for speedy levelling or indeed a mount when I reached 30.
By investing a small amount of time at the end of each play session checking the current AH price of the items I picked up, I soon learnt the true monetary value of those items. Not just the more obvious ones like cloth and leather, but also items such as citrine and shadow gem. These items have uses in professions that make them desirable to certain players and can attract considerable amounts of income.
I now regularly put items in the auction house for the going rate. PLEASE don’t undercut everyone and drive down the value of the goods you are trying to sell. I usually start my play session at the mailbox where the postman has kindly delivered heaps of gold for things I used to sell for just a few coppers.
Hope this is of some use to someone. I’m sure the rest of you aren’t daft enough to fall into the same trap although in my defense it was before I had access to the “Communal Guild Brain Cell”

Oh and if you ever need rezzin whisper me as I suffer from a resurrection addiction and simply can’t get enough. (You can delete this bit if you like Nim as I appreciate it’s not really relevant.
