Uh, sourceforge? When I hear "making these files available" I think github or a simple website. Not something with a download.com-style "Wait 5 seconds while we force this ad down your throat and try to find a mirror because Route 53 / load-balancing is a foreign concept to us programmers still hanging out in the '90s."
GitHub is more popular for code management of underpinnings (think jquerry, twitter backend stuff, etc) but SourceForge is far more popular for actual apps. Nearly all the most popular GitHub projects, if you click downloads, you're met with "There aren't any downloads yet. But don't worry! You can download the source code as a zip or tarball above." SourceForge, on the other hand, is all about apps, usually cross-platform, that users can download and use (VLC, Pidgin, GIMP-Windows+Mac, OpenOffice, Inkscape, KeePass, etc). So, I think GitHub is more popular with coders, but SourceForge is far more popular with users and app makers.
