OpenStreetMap

What do you like best?

It is free. It is based on community input and I think this map is the most accurate as of today. There is no need to go through approval process with your edits. This is important as your work is immediately accepted and visible. Comparing to other similar products your changes might not be approved and that's not very encouraging. It has a web interface to edit the map. Anybody can use the map free of charge.

What do you dislike?

I guess it is a bit hard to start with editing the map. The tools and symbols are not all intuitive and you need to follow a guide before starting.

Recommendations to others considering the product:

What problems are you solving with the product? What benefits have you realized?

Having an accurate map is important when looking for an address for example. Some other services might not have most recent details, whereas Open Street Map has more accurate details.
