I'd be shocked if this were downvoted, as Lesswrong's affiliation with your charities is probably the best part of this website from a utilitarian standpoint.

So, I see that you use various sources to determine the optimal charity. Via GWWC, I found links to GiveWell's review via the site, and I notice that they post the results of their analysis next to each charity. Is your meta-analysis posted somewhere on your site as well?

If not, it should be, and more prominently featured! Your target audience are the type of people who would seek out a meta-charity, they would need to see those papers. It's important that a given viewer can, with relatively little effort, be relatively assured that the claims of the meta charity are accurate.

As a user of the web-page, I'd like an accessible, concise summary of how you know that your top recommended charities do in fact have the best QALYs/dollar ratio, as well as a resource for more thorough investigation. (And apologies if this information is on the site and I just didn't find it - but if I didn't find it then it's likely others are having the same issue!)
