Depends what you are trying to achieve.
If your application lends itself to having the data normalised to 
fixed time intervals, stored efficiently, and plotted on good quality 
graphs - then yet it may be of use to you.
If not, then no it probably isn't the right tool.

It would probably help you understand what RRD does, and decide if 
it's useful to you, if you took a look at Alex's tutorials :
Specifically, "Rates, normalizing and consolidating" explains how it 
handles data that doesn't arrive on nice regular time interval
