Microphilanthropy is a model of philanthropy that is based on smaller,
more direct interaction between "helpers" and "doers." Because of this
finer level of granularity, it provides greater potential for feedback.
It uses the definition of philanthropy as "love of humanity", which is
broader than just charity or donating money. This opens up a broader
range of activities such as volunteering, emergency response activities,
mentoring, and many other patterns of uplift. - Wikipedia
