The Gold Gifting System drives me crazy. I have 2 reliable people that I trade with every day, and then there are about 4 or more who toss one at me every few days. When they all do it at once I'm stuck with a decision, and having to decide who gave it to me first, last, most often...yada yada yada. It's so distracting that I almost wish I could just buy some gold and give that to them.
I usually favor the newest players, if I can. Seems like they might benefit the most from tiny gifts.
