Show HN: Who will match my donation?

This site shows an up-to-date list of (hopefully) all accredited non-profits which are currently matching donations.

I was motivated to make this because I found it difficult to find any resource for listing which accredited non-profits were currently matching donations.

The code for this site essentially cross-references all established non-profits on Charity Navigator with their associated Twitter handles and then uses their recent Tweet stream to determine whether they are matching donations.
