Where should I put the prime meridian?

So I've just sent a probe to map a new Earth-like planet, and I'd like to establish a latitude-longitude standard for the planet. The poles are pretty easy to spot since the planet is rotating, so I plop down the equator halfway between them and boom
, I've got my latitude lines laid out. But now it's time to lay out the longitude lines and I need to find somewhere to put the prime meridian. How do I decide where to put it?

I'd like to think of a reasonably standard way of deciding where E 0° should be, and it should also be easily communicated, so that other people using probes can sync their maps and measurements up with mine. Any thoughts on how one would go about this?
