To some extent SoGive will be implementing what you’re suggesting. As well as the overall top, EA-recommended charities, we are also looking to identify the best charities within other cause areas (e.g. poverty/homelessness in the UK, developed world health, tree-planting charities). Ideally we want to nudge people to switch to the overall top charities regardless of cause area, but we know that a lot of people are very committed to a particular cause, so it could be quite valuable to help them at least identify the top charities within that cause.
