There are a number of rating sites out there, sometimes with conflicting information. What do you go to when you want to donate, especially when you want to look for a particular issue/crisis/disaster.
If I can improve my impact by taking a few minutes to research, it would be nice to have a place to go instead of googling “charity rating for ____”
And those charities around me work on local issues, whereas I want to support the less privileged
Then you can help gather more people, make more people aware and meet people that for example fled, have relatives or friends in those countries etc. In the end you may not spend a cent but quality time with nice people, help make the network grow.
If you convince two people to donate, you doubled what you would do alone.
