Disclosure: I work on location products at Facebook. I think that real world places are an important part of who you are. Where you're from, where you've lived, and where you've travelled to, for instance, all help tell a story about you as a person. The way that's represented on Facebook today is the Map on your Timeline. These suggestions help you put more photos on your map so you can share experiences with friends. That trip you took to Disney World 5 years ago may be far down in timeline, but it's going to be easy for friends to find it on your Map. Hope that helps explain the "why" a bit.
