Blogger’s Note: This is the first in what will be a series of posts looking at what’s been called Longtail Philanthropy or Network Philanthropy — aggregating smaller efforts to produce larger impact.

Been to a “meetup” lately? Even if you haven’t, you’ve likely at least heard about Meetup.com — a social networking website that helps bring together people who have similar interests and happen to live near one another. The site is useful if you want to find a hiking group, a book club, or a wine-tasting event; but we’re also seeing more and more groups coming together not just for social networking, but for social good.

The Whole Can Be Greater...

Head to Meetup.com and search for Philanthropy: there are 76 already-formed meetup groups in 60 cities and 3 countries. These run the gamut from groups who get together to volunteer for charity, groups who pool their cash to give larger amounts to charity (these are commonly called “giving circles,” and we’ll talk about them at a later date), groups that like to talk about social entrepreneurship and venture philanthropy, groups of non-profit workers who get together to discuss fund raising, etc.

So, if you’re new to philanthropy — or are trying to figure out how your $10 per month or 3 hours per week can make a difference in your community, city, state, or country — consider finding a meetup in your area with like-minded folks. You might be surprised what happens when the whole is more than the sum of its parts.
