The Open Philanthropy Project is aiming to fund research. I'd prefer to let them do the research working out where to donate, rather than picking scientists myself.
See, I'd prefer to do the research myself and have a relationship with the scientists.
OK, but that is entertainment, not charity of philanthropy.
No, I would see that as taking the initiative to actually understand the projects that you're funding for yourself. In doing this you become more invested in that cause and the community surrounding it.
