What are some free FUN apps for my ipod?

[Short!e]

I just got an ipod touch, I really like to talk to new people and get to know others...
Is there any apps that can let you talk to others?

Also, is there any fun apps like farmville? Those games were you have to take care of things??
I only have farmville on my facebook.
