That isn't the main return for me. It is knowing that you have contributed to the community corpus of knowledge that is almost impossible to come otherwise. For instance I had the to visit a data centre that I had previously been to but was under a new owner. The pin had Equinix but not the site code. Once I confirmed it, I submitted the edit for it to become Equinix SY6. It apparently has since been used thousands of times.

I also enjoy adding a food shot or a representative photo of places I have enjoyed as a small reward and enticement for others to do likewise.
