I lived in UB for a year and have visited on and off for the last 10 years. Its VERY easy to meet people in Mongolia. But please note about 50% of the population now lives in UB. That said, in the summer time (very short period!) everyone likes to spend time in the country side. So there is much enjoying, relaxing etc.
In my experience traveling around Mongolia, somehow, no matter how remote, there was always a horseman (maybe now a motorcycleman!) around to find out about you - what you were doing there, where you were from etc. There were children and older people in the countryside. And yes..language was an issue...many people could speak Russian then, now I don't know. So go and visit. Every Ger will welcome you. Bring something as a small gift to leave.
