Not to comment on the merits of this particular charity, but the important part is the feeling of doing meaningful work rather than the meaningfulness of the work per se. Part of this is feeling that you are contributing something unique to the cause yourself. I do not believe that writing a check each month would make you feel that you were doing anything meaningful (after all, many people are capable of writing a cheque).
