We have discussed this here and all weight loss is not the same. It depends on how far the weight is from the CG of the bike as well as whether or not it's sprung or unsprung. If weight loss is your passion, the most impact generally comes from wheels. The lighter the wheel the better, or at least quicker the handling basically.
Unsprung weight means the weight on the bike supported by the ground, with sprung weight being the parts of the bike essentially riding on the suspension's springs. The biggest negative impact of unsprung weight is controlling the unsprung mass since it is not dampened by a suspension damper. Essentially when a wheel bounces, the heavier it is the harder it is to stop the unwanted motion. What that boils down to is the wheels skip over bumps rather than following them and traction and control are reduced.
So long story short, these few ounces are "valuable" ounces IMHO as opposed to something like CF mirrors. I rode my bike with and without the titanium axels and the difference is noticeable if slight. There is a smoothness to the feel. Now, this could be more due to the flex properties of Titanium, which I am told is better for this application than steel.
