This is a derivative of Source Sans Pro which, since modified, has had
its name change.  The following changes have been made:

1) Subsetting.  Only English and Spanish are supported.

2) No bold italic.

3) No open type (Open type renders poorly in Windows, even Windows 7); only
   true type .ttf files used.

3) Bold here is semi-bold.

4) Semi-bold rehinted with ttfautohint, to make it stand out more from the
   regular weight on Windows machines.

5) Tighter line spacing.

6) ttf -> woff conversion redone.

7) woff directory includes a simple html file showing the CSS to use 
   this typeface.

This is the web font used at samiam.org.
