I know it was a donee last year, but I don't think any project fits "mainstream privacy", "making privacy tools for the general population" or "relatively small contributions make a clear difference" than Mailpile (http://mailpile.is).

Small team and a set of philosophies on privacy, freedom and UI/UX design that are sadly rare if existant elsewhere.
