Sense of community. I used to have the belief that being an anonymous donor, giving money to charities quietly, was the right and noble thing to do. Then there was the Ice Bucket Challenge and I realized that an individual donation is nothing compared to the multiplying effect that comes from having others within your community and network join in, and that requires finding creative ways of signaling your donations to others. Some find it distasteful to signal this, but the problem is that the end result of signaling donations is so much more effective that it's worth it.

Joining a community of people who also pledge to participate in charity and promote charities to one another could be a way to eliminate the distasteful part of signaling to others that you donate to charities. It can also work as a way to integrate charities and donations as a routine part of your expenses and budgeting.
