Sometimes, when an MMO is new and all the mainstream PLVL ME LFG WTT WTB WTS cigarettes have not found it yet, there is a good core community and you can have a good time talking to people even while grinding.
In Hero online I was one of the best know players on a server (I was actually taken into a major House just because they wanted to have all the people who were well-known.) and I was only level 40 or lower. Most of the other people were 50-90.
Similar happenings in Conquer Online, and various other RPGs. It's just a question of having people to talk to while you grind. And every now and then you might do something as a group, which is always fun.
