Also, a radiotelescope on the far side would be shielded from Earth's interferences. While that would be really awesome, I'm pretty sure a radio telescope could be shielded just as well with a few sheets of metal (like the James Webb telescope). And if it's stuck to the surface of the moon, it's a lot more restricted in where it can point at any one time than one free-floating in space would be.
