Filter local meetups by various variables within the ACS 5-year data down to the block-group (enabled by zooming into the geographic area).
By mashing these two APIs (http://www.meetup.com/meetup_api/, http://www.census.gov/developers/data/) together, community builders can identify groups and leadership/influencers that exist within areas of interest. Hopefully enabling a sort of distributed knowledge management system.
In this example application, it is assumed the community builder is a proponent of ‘Asset Based Community Development’ and is seeking to find groups upon which to build to improve communities that have high rates of poverty.
I welcome any collaborators to make this rough concept better by making it your own.
