It means your attenuation (effectivenes of the yeast doing its job) was better than expected. Low FG doesn't mean it will have less taste, it may be a little dryer, but that doesn't mean less taste.
Yeasts are assigned an attenuation estimate...usually between 65% to 77%. THe higher the percent, the lower (or more fermented) your beer will become.
Take the difference between your starting gravity and final gravity and multiply that times 131 and that will give you your ABV%.
