My rear derailleur started skipping around today. Being relatively inexperienced with this problem, I was wondering how one goes about fixing it. Can I do it myself (how? and what tools should i need?) or should I take it to the LBS for a free tune-up? The bike is relatively new, but I bought it off the floor, and I suspect that in the middle of the giant fourth-o-july sale in which I bought it, the derailleurs were not properly adjusted or simply overlooked due to overload. I figure I should look into it before disaster (a la mr. derailleur, meet mr. spokes) is my story.

What you should do is take it back to the shop and tell them what "skipping around" means. I know that other thread you referred to mentioned that, but I have never heard of the derailleur moving, say, side to side on it's own. Maybe the chain will jump around a bit if the shifters are misadjusted or the cassette is worn. Have it checked out, since the first is very likely. especially with a floor model that gets messed around with by customers.

I'm the "Mr. Derailleur, meet Mr. Spokes" guy. Get it fixed! Fast! If you do indeed have a free tune-up available to you, there's no excuse not to have someone look at it immediately.
The last sound I heard before my problem was the derailleur skipping. It didn't skip long before disaster struck.

You should definitely take it to the LBS for a free tune up. Incorrect cable tension is the most likely culprit. A stiff link in the chain is another.

This is more what's happening. The chain is jumping from sprocket to sprocket. I have an SRAM 7.0 11-34t rear cassette, Shimano HG-53 chain, Deore derailleurs, and a shimano 44-32-22t crankset. The skipping seems to occur with 44-12 and 44-14 (the two penultimate small sprockets). Can anyone spot a problem with this setup, its stock from the manufacturer, so there shouldn't be anything wrong with it, but maybe there is.
thanks all. turned out it was maybe half a turn on the cable housing and the problem appears to be solved. out-of-the-saddle sprints (sheldon brown's "cause"😉 now no longer have the skippy-chain problem...it was very disconcerting when it happened, glad it was a minor adjustment.
