I'm a nonprofit advocacy guy -- PIRG, Sierra Club. There's a huge need for tools that small to medium sized nonprofits can use to help them with backend operations. Eg, member databases -- Salsa et al are very expensive and deployment costs are high for small group. Or financial mangement -- Quickbooks is also expensive. Even basic IT tasks.
There's a lot of activity around nonprofit software and tech tools. It seems focused on how to use technology to *add* to what nonprofits are doing, which is great. There is an equal or greater need for tools to help nonprofits make their core business operations more efficient and robust, and a need to educate staffers on the tools that already exist. How many nonprofit people know about GIMP?
